Funnily enough, I was soon going to create a thread on how there may be a side to Broly's character few consider that may make his M8 self not as bad as he often gets flak for, but that can wait for now.
For this remake, I'd place it about a year after the Boo Arc. Whilst I'd like to place it in the 9 days wait for the Cell Games, there's very little time to squeeze it in with all the events that were already crammed into those days such as the Rosat trips and Dragon Ball gathering. Putting it in the 7 year Post-CG gap could work, but it'd sacrifice the Goku element from Broly's character.
That said, much like the original movie, it starts with Paragus finding Vegeta and hailing him as the new Saiyan King, requesting he deal with the Legendary Super Saiyan that has been ravaging space. Goku looks in puzzlement whilst Vegeta laughs at Paragus' serious tone, the two transforming into Super Saiyans and telling Goten and Trunks to do the same, Vegeta declaring the Super Saiyan isn't as "Legendary" as it once was. Paragus is surprised, but tells them that this Super Saiyan is something far different, much to their shock. The group of Vegeta, Goku, Gohan, Goten and Trunks head to New Planet Vegeta and the mystery element of the original movie remains with nobody being sure about Broly. In this story, whilst greeting the guests, he immediately leaves after doing so. Paragus tells them that his son is shy but strong, the two having learned the martial arts of many alien worlds they have visited. It's not long after that one of Paragus' men states that the Legendary Super Saiyan has been found, causing Vegeta to head out to their location.
Vegeta finds the Super Saiyan they spoke of, a giant, muscular Super Saiyan with an appearance similar to Broly's LSSJ state but with a more mutated appearance. He easily defeats it without transforming into a Super Saiyan and spares it, saying that Freeza would've never been concerned with the Super Saiyan if this was the reality of its power. Goku and Vegeta then discuss what to do with him, in which the words "Vegeta" and "Kakarotto" are mentioned multiple times. It isn't long before Broly screams and transforms into a Super Saiyan, killing the unknown Super Saiyan with a Ki blast and rushing at the two. Paragus laughs and tells Gohan, Goten and Trunks that Broly is indeed the true identity of the Super Saiyan he spoke of and that he won't rest until their fathers are dead.
We then have a flashback to the time of Broly's infancy, with the plot events being quite similar to in Movie 8. Kakarotto's crying upsets Broly and being stabbed by King Vegeta fills him with rage. As he grows older, these two early memories stay within his mind, how a low class Saiyan could get under the skin of one born with power many elites don't reach in their lifetime and how the jealousy of a king undeserving of his role almost lead to Broly's death. Throughout the years, he spends time ravaging planets on the far reaches of space, though Paragus creates the crown to control him and has him used as an attack dog to gain resources. Though they could simply find Freeza and kill him at some point, Paragus wanted to gain all he could to put fear in the hearts of the surviving Saiyans and create an empire far greater than Freeza's from the shadows, finding a scientist capable of creating a clone of Broly; albeit, far weaker and mutated.
As Goten and Trunks attempt to rush in and help their dads, Paragus stops them and powers up, revealing he has learned to control his Ki. He is able to put up a fight with the two boys, revealing how training with Broly allowed him to achieve power he never thought possible for anyone but his son and as they transform into Super Saiyans, he shoots them each with a stun gun, revealing it to fire the same electromagnetic shockwaves that help keep Broly under control. Taken off-guard, the kids power down with Gohan stepping in. As this is going on, Goku and Vegeta are fighting Broly as Super Saiyans and being pushed back. They gain the advantage by going into SS2, but after seemingly being defeated, Broly powers up and adapts to their power. As the battle rages on, he ends up breaking the limit of his crown and transforming into his LSSJ form, gaining everyone's attention. Goku is shocked at the Ki he senses, whilst Vegeta immediately resigns himself to defeat in seeing it as his M8 self did, his far stronger link to Saiyan society making him know just how terrifying Broly is. Even as a SS3, Goku can do nothing and the combined efforts of Gohan and Gotenks end up meaning little too. Goku then proposes everyone lend him their Ki. Unlike in the original film, Vegeta complies, thinking it may have a shot. Whilst it does end up making Goku far stronger (and offering foreshadowing for BoG), it's still nowhere near enough to do anything to Broly. It's after Broly takes on the powers of many Super Saiyans whilst his Ki continues to rise that Vegeta even questions what their Super Saiyan form is, wondering if it's just a pale imitation of the true Super Saiyan before them. Given no option, Goku uses Shunkan Ido to bring everyone to Kaio's planet, with Kibitoshin then arriving to bring them to the Kaioshinkai.
They then question how they are to deal with Broly. If not stopped, he will continue ravaging the universe. They bring up the ritual as an idea, but agree it will take too long and not matter when even Gohan was helpless. Goku finally brings up fusion, requesting that Vegeta throw aside his pride and fuse with him again. Vegeta isn't listening, not for the reason of his pride, but at the sheer amount of fear Broly put into him. After words of encouragement from Trunks, however, he finally decides that if he wants to protect the family he decided to have as the new legacy of the Saiyans, he must first defeat this reminder of the Saiyans' past.
Meanwhile, Paragus decides to leave the planet after his enemies flee. Broly, however, stops him and the years of being controlled cause him to lash out at Paragus; as Broly crushes his father's head before letting out a bellow that cracks the dimensional fabric around him much as Boo did. He then jumps through it and enters the afterlife, attempting to track down Goku and Vegeta's Ki signatures.
Sensing this, Goku and Vegeta are given no choice but to succeed with the dance on their first try, being given no second chances. With the knowledge Vegeta had from watching the dance from the afterlife in the Boo Arc, they succeed and Gogeta is formed. Gaining Ki from Gohan and Gotenks once more, Gogeta faces off against Broly one-on-one, declaring the two Saiyans Broly's rage is targeted against are now one man ready to defeat him. The fight between the two is intense, with Gogeta's attacks pushing Broly to new heights. Keeping the fight in just his Super Saiyan state, however, Gogeta carefully makes sure Broly's body can't adapt to a full power Big Bang Kamehameha from his SS3 self. Whilst Broly comes close to catching up to it, the power up is too sudden and he eventually succumbs to the attack, being completely destroyed. The energy lost is enough for Gogeta to immediately diffuse.
The story ends with Goku and Vegeta discussing the Super Saiyan form, wondering if he was the Legendary Super Saiyan, what does that make them? Goku then reminds Vegeta of their training in the Rosat, how ascending beyond what they thought the Super Saiyan limit was became possible and concludes that perhaps what they have right now is just the first few steps of achieving the dormant power of a true Super Saiyan, offering some slight build up to Super Sayan God.

Fan-fiction of the worst kind? FnF is a worse offender with even worse writing. That movie was all fan-service too and didn't even do that good.
At least in FnF, Freeza having never trained a day in his life and still having at least a 120mil peak acted as some justification for his gains when even Gohan had to train intensely to gain such power. Meanwhile, Broly's only training was with a beast who was at best somewhere between 5-10k, yet he's able to fight against God Ki users even without Super Saiyan.
FnF didn't damage anyone's character permanently either, unlike DBS Broly ruining Freeza beyond repair through his asinine reason for abandoning immortality.
