Well, it's finally time to make on to the Tournament of Power Arc.
(General reminder that the OP states the lowest score possible is a 1/10, before everything jumps in with 0/10s. Even if they do, they'll be treat as a 1/10).
It goes without saying that like all of Super, the arc has no tension due to the inherit flaw of placing a series before the end of Z and obviously plot armouring all the main cast because of it. This flaw could've been avoided had the main point of view been changed to one of the other Universes to add a sense of drama by fleshing out their characters. Unfortunately, nothing of the sort happened as all the characters from other Universes were 1-dimensional and only a handful weren't fodder to the bulk of the U7 cast, making the hype that had been given for there being other Universes near the start of Super completely hollow. Moreover, none of the fights were entertaining as despite having advertised itself as a battle royale that would require tactics, it never delivered in that regard and the closest thing to a tactical manoeuvre would be Freeza and #17's teamwork against Jiren.
On the subject of those U7 characters, talking about them helps show the quality (or lack thereof) of the arc. Boo's absence for a rehash of his role in the U6 Arc and his role in the ToP could have helped the writing quality by his healing excusing Goku and Vegeta not going down easily and having the stamina to keep powering up. Kuririn, Ten and #18 weren't given much focus in terms of general use or characterisation, so moving along. Piccolo was wasted by being caught off-guard by Damon when #17 could hear him despite Piccolo having always been the member of the main cast noted for his hearing, not to mention #18 couldn't hear Damon and was taken out by an off-guard attack. Gohan's power up was ridiculous of going from his Boo Arc Ultimate level to SSJ Kefla's equal just from adapting over the course of the battle. Where was that skill when he was getting stomped by Gotenks Boo?
Taking a detour and talking about Kefla, Potara showed the arc had no sense of internal logic. Any rules in the ToP were quickly thrown aside if Zen-Oh just found it "cool" such as Potara.
Back on the main cast, Roshi's character arc was ruined. His role of retiring from the battlefield after reaching his peak and falling behind was a decent end to his development, yet Super ignores all that by having him being the most skilled member of the main cast to the point of taking on Jiren and even in terms of physical ability, he had improved to a level he could still dodge Magetta's attacks. This would have been excusable had he always been shown to be a fighter who's skill had been honed from his centuries of experience, but this is a guy who almost lost to 12 year old Goku who had only a basic or adept martial arts skill. Vegeta regressed a lot in this arc with how much he focused on "muh pride" like his Cell Arc self despite that completely going against his development at the end of the Boo Arc and his asspull of Super Saiyan Blue Evolution was pointless when it changed nothing in the plot. #17 was practically a Gary Stu, often being the one in the spotlight such as having better hearing than Piccolo and being the one to take home the win with his unforshadowed strategy, as well as awkwardly being revealed to be PSSB tier at the end for little reason other than Toriyama liking him. His wish to revive the other Universes also left there being no consequences from this arc. Freeza also had barely any role in the arc beyond trolling people and being arrogant, which no longer had any impact after being revived for the 3rd time offered nothing new to his character and made a once entertaining villain completely stale.
Finally, there's of course Goku. Despite the stakes of the battle for he and the other Universes, he never seemed to hold any responsibility for his actions despite Universes being erased and his Saiyan/Freeza/Cell Arc self having felt a lot of anger towards the death of even a few hundred innocents. Along with that, his Ultra Instinct transformation came out of nowhere and ultimately proved useless when it was neither a permanent power up nor what defeated Jiren. From a plot perspective, Jiren needn't have been Hakaishin tier when he wasn't a permanent benchmark Goku surpassed in his growth of power.
Overall, this was just as pointless an arc as any of Super as nothing was lost or gained from it, with it having taken the current spot as worst arc of the Dragon Ball manga (except maybe DBH material I have no interest in).
1/10
Anime-wise, things were far worse. Going back to the characters of other Universes, they were made even worse. Whilst given more attention than in the manga, it backfired as aside from Obuni, Saonel and Pirina, they all went from having sympathetic qualities to being completely villainised when facing anyone from Universe 7 or 6. It didn't help that so much time being given to these fodder slowed down the pacing of the arc heavily, especially Ribrianne being one of the most pointless and annoying characters in the franchise. Also, despite taking more time to build up the characters from the other Universes as genuine threats, all but Jiren proved irrelevant. Damon's initial absence tried to hype up Universe 4 as the true threat only to be an episodic villain. Kale was hyped up as being MAXIMUM only to be about SS3 Goku level, etc.
Going back to the U7 cast, the anime made them all far more inconsistent or incompetent bar Roshi. Kuririn let his guard down completely despite knowing the danger and #18 proved of little use in defending her husband. Tenshinhan was made even more pathetic by losing via double-KO to a forgettable character rather than being beaten by an established character like Frost. Piccolo was made more inconsistent as despite using his arm stretching to save Gohan, he never used it to save himself. Goku had a few problems in this, but I'll get into that later. Gohan was made completely inconsistent and disappointing as despite having been initially presented as changing and balancing between a family man and warrior, all that development became pointless when he kept relying on other characters and holding back for little reason. Vegeta's regression was even worse in the anime with how he only started thinking of his family very late into the tournament and was given far more plot convenience with how he lost no stamina permanently from spamming SSBE and using Final Explosion. #17's plot armour was even greater with him going from SSB tier at best to taking on Jiren alone and unlike his manga self, there was no stategy in his explosion and he only survived because of plot armour. Freeza was completely ruined as despite the complete hatred he had for Goku and the other Saiyans, he ended up just becoming a grumpy ally by the end like Cell Arc Vegeta when he had no pivotal moment of change to cause this.
Finally, we have Goku and everything about him was worse than ever. Unlike the manga, which points out he was the one who essentially saved the lesser Universes from inevitable destruction, the anime makes the other Universes completely braindead by blaming him for being the one to give them a fighting chance. His conservation of stamina was even more of a poor way of prolonging the plot, especially when he had no reserve in immediately going SSB whenever it was required, but despite having Shunkan Ido, he hardly ever used it for saving allies from falling out the ring. On that point, most characters with abilities to save them or their allies from ringout, when they were in the position to use them had no logic and was pure plot convenience. Also, his way of achieving Ultra Instinct was just as stupid as the manga as being damaged by the Genki-Dama contradicts the Saiyan Arc usage of it and him powering up through being hit by it had no real foreshadowing. Also, despite it being a drain on his stamina, he never really ran out and instantly regenerated it most of the time.
The only U7 character better than their manga self was Roshi, since he at least provided a reason as to why he was no longer in retirement, though even he was ruined overall with his power up coming out of nowhere, his spamming of the Mafuba making Zen-Oh's care for rules even less, the moment that could've lead to his death being something that could've and didn't provide more drama and the Yurin episode practically turning him into a rapist.
Also in terms of new characters, there were a few stand outs in terms of terrible. Jiren was far blander than his manga self with how all he cared about was "muh strength" and Toppo was made inconsistent with his asspull power up coming from abandoning his justice when he made apparent to Dyspo a dozen episodes prior justice no longer mattered.
Along with all that, things were made even more pointless with how the requirement of the winner's wish being a benevolent one made any sense of tension or loss in the arc even more worthless when there was never any threat. Absolutely hollow and leagues worse than the manga version. If I hadn't already made it apparent 1/10 was the limit, this would be a definite 0/10.
