Since I've already gone into detail on the films in the Review thread, I won't explain too much about the ranking (though some rankings have changed since then) and won't include the two TV Specials.
#1 - Mystical Adventure - Decent retelling of the 21st/22nd Tenkaichi Budokai. Simple, yet well executed. Pretty funny how Chaozu has way more going on for him in this film than in all other parts of the franchise combined.
#2 - The Path to Power - Nice retelling of early Dragon Ball with nice animation that helps make #8 into a relevant character, though Goku's rage boost at the end makes for a rushed climax. Pretty interesting how they utilised #8, as I believe rewriting #16 as #8 with some major upgrades in the Cell Arc would've resulted in a lot more character drama in his programming to kill Goku, provide a reason for him to later bond with Goku and Gohan and thus make his death more tragic than the bland #16 we got.
#3 - Sleeping Princess in Devil's Castle - The antagonist's motivations are a bit questionable, though the film otherwise succeeds at being a fun action/adventure that captures the core elements of early Dragon Ball.
#4 - Fusion Reborn! Goku and Vegeta - Has good action, but its plot is dragged down by Janemba being a Boo clone and the comedic scenes of Veku's plot armour having him survive against Janemba clashing tonally with the previous part of the main battle.
#5 - Bojack Unbound - Despite being a Cell Game rehash, it's at least somewhat consistent in both fitting into the main timeline and being straightforward in its execution, though Bojack and his crew getting to Earth from whatever part of the galaxy they were in despite having no means of getting a spaceship. Still, at least having a villain of long ago that was sealed away offers a concise reason for Bojack being so strong yet never mentioned prior, which is more than can be said of a lot of previous and later villains (*cough cough* Slug and DBS Broly *cough cough*).
#6 - Tree of Might - Has some problems in power-scaling (Tullece not making note of Kaioken x2 Goku against Oozaru Gohan yet treating base Goku as a big deal) and using a Saiyan as the villain could be seen as repetitive immediately after the Saiyan Arc, but the plot's execution is decent enough and some elements add to the world building such as the Shinseijuu being an interesting concept and lower-class Saiyans all being fairly similar genetically links well with what Toriyama would say about the Saiyans' low population. The mention of Tullece wanting to surpass Freeza also helps give Tullece more motivation and make the movie's world feel lived in and expansive, unlike a lot of other DBZ films.
#7 - Cooler's Revenge - The concept of Coola slots nicely into canon and he's given a lot more personal motivation than someone like Slug, Bojack or Janemba, though his personality is still just Freeza with his core character traits removed and Goku not being able to go SSJ at will was dumb. Shame, considering later implications about Coola would've helped make him more of an engaging character (eg. Freeza and Cold being described as the prodigies of their race and the Armoured Squad not being described as mutants like Jheese and Ginyu retroactively give Coola's faction compared to Freeza's an effort vs talent dynamic).
#8 - Return My Gohan! - Garlic Jr.'s backstory and role gives him better motivations than all other movie villains and adds somewhat to the series' world building, though him wanting to kill Piccolo before using the Dragon Balls, Kami attempting a suicide move when Gods aren't allowed to kill themselves and the main fight being a rehash of the Raditz fight gives the film more cons than pros.
#9 - The World's Strongest Guy - The movie doing the mad scientist plot line long before Gero was mentioned in the manga makes it more interesting in retrospect and it at least doesn't rehash as much material as a lot of later movies, though the elephant in the room of Uiro's huge brain fitting in Roshi or Goku's body makes the villain's motivation laughable and whilst not being much of a rehash of canon events, it does reuse the rescue plot of the last film and Piccolo being taken out at the end, not to mention Piccolo being mind controlled was pointless.
#10 - The Legend of Shenron - Could've been a decent retelling if not for Pansy's role overshadowing that of the main cast's motivations.
#11 - Broly: The Legendary Super Saiyan - Broly makes for a good concept. Unfortunately, the execution with his motivations is very lacking due to the infamous Goku crying drive, though there's at least some level of rationalisation of it if
#12 - Wrath of the Dragon - A new character being brought in through Tapion was a nice idea to shift things from the typical plot armouring of the main cast against one-dimensional foes and the bond between him and Trunks, as well as the lore behind Hildegarn, gave it more story than a lot of the other DBZ films. Unfortunately, this is overshadowed by the extreme amount of plot armour (even Videl survived hits from Hildegarn), Goku holding back SS3 until the end and then winning with an asspulled new attack.
#13 - Battle of Gods - Beerus made for an interesting new addition, though doesn't make up for the further retcons of the God hierarchy, Vegeta's contrived rage boost and the power up of Super Saiyan God being far more of a ridiculous asspull than anything that came before it.
#14 - Super Saiyan Son Goku - Main villain is a Piccolo Daimao knockoff with the motives of a Saturday morning cartoon villain and having this be the third villain in a row to lose to the Genki-Dama (especially when the film produces its own version of Super Saiyan for Goku to use) is mind-numbingly repetitive.
#15 - Return of Cooler - Coola's survival was an asspull, the Metal Coola army battle being skipped over is a huge disappointment and the way Coola dies makes him extremely incompetent.
#16 - Super Android 13 - Has zero plot beyond "more androids want to kill Goku" with these androids having absolutely no defining character traits, Gohan is made useless despite being at least of semi-relevance in past films and #13 is a poor Cell clone.
#17 - Resurrection F - Freeza reaching God Ki tier with 4 months of training is ludicrous, the main fight is a Freeza Arc rehash and any consequences are ruined by time resets.
#18 - Bio Broly - Considering how Broly was treat in the film, there was no need to have him in it beyond brand recognition.
#19 - Broly: Second Coming - Pointless filler side plot at the start and Broly's characterisation is reduced down to "KAKAROTTO!"
#20 - Dragon Ball Super: Broly - The fact this is meant to be canon hinders its overall quality due to irreversibly ruining Freeza's character, going with the Minus backstory damaging the previous perceptions of Saiyan society, Broly having zero character once becoming enraged and overall being filler even by DBS standards.
to me.
