Was alright. Broly's backstory is better than the backstory for most movie villains and leagues better than Bibbidy or Jiren, it actually has some connection to the stuff we already knew. That said, as a character Broly is hardly interesting. He never seems to have any agency at any point in the movie. All his actions are either dictated by Freeza, by Paragus, or by his own insanity. And that denies him a bit of depth or growth. There also isn't much connection between his backstory and his motivations in the fight. He doesn't have motivations other than just to smash everything, there is no personal connection tying him to either Vegeta or Goku. Only between Broly's dad and Vegeta's dad. It makes Vegeta and Goku quite bland as well, they just fight back, but they can't bounce off Broly personality-wise at all. There is no dynamic there.
I'm also not fond of them rehashing the same formula once again for Goku and Vegeta fighting a powerful foe and Vegeta not wanting to fuse. They've done that like three or four times earlier already and it was the exact same thing (Super Buu, Omega Shenron, Janemba, Zamasu). The dynamic between Goku and Vegeta also just isn't all that interesting, it's been done so many times and this movie didn't offer anything new there. Goku says dumb things and doesn't take anything seriously and Vegeta gets annoyed by it and calls him dumb. Why Gogeta just let Freeza go, I don't know. It doesn't make much sense considering how Vegeta viewed Freeza earlier on in the movie. And then Freeza comes to Earth in an attempt to kill them, proving he's still evil, and then he suddenly lets him go? Goku letting him go I can sort of get, Goku is an idiot and he always does dumb things like that. But Vegeta?
Goku and Vegeta failing to fuse twice and having to spend over an hour away from the fight as a result comes out of nowhere and it makes no sense Freeza holds out that long against Broly. It makes no sense. That's longer than the entire Tournament of Power. And it is like two minutes in movie time. It definitely doesn't feel like an hour. I've got no idea why they added the failing to fuse twice gag, it's just a rehash of the Gotenks stuff from the Buu arc except there they could get away with it as there wasn't such a time constraint. It breaks suspension of disbelief and also broke the tone right before the climax by going for such cheap gags.
The Dragon Balls only giving one wish this time is also weird. I think Dende's Dragon Balls have given anything from one to three wishes on a summon depending on the plot demands and medium, no idea why something so fundamental to this series that it's actually named after them is so ridiculously inconsistent on their most basic function of granting wishes.
The fighting itself looked awesome though. I'll give the movie that. Visually it's spectacular. The Gogeta portion was weird though, I've got no idea what they were doing with the background there and why they were suddenly in hyperspace or whatever.
Overall, I think the primary complaint I have is that this movie has no tension. It has spectacle, but that spectacle has no substance or plot relevance. It's just spectacle for the sake of spectacle and fanservice. You already know from the start that Goku and Vegeta have blue god forms and they're not using them for the longest time. You see Vegeta go from base form to gold to red, and then when you think blue is finally next they switch to Goku and just repeat the whole sequence. It's a checklist of forms they have to get through for marketing, but doesn't advance the plot. And with Goku and Vegeta holding back for so long there is no tension, because the main characters aren't taking it seriously enough. And then once blue finally shows up it's over quite quickly and doesn't deliver, it's just the same with a colour swap. And you know that Vegeta still has the bluer form (which he doesn't use) and Goku still has the Kaio-Ken (which he also doesn't use because auras don't translate well to action figures). And then they go to the fusion part and they turn it into gags, draining any kind of calm-before-the-storm setting and draining tension by just goofing around for over an hour in-universe (hour downtime after defusion is apparently retconned out). And once they finally manage to fuse successfully, there is STILL no sense of hurry as Gogeta feels it is more important to think of a name for himself than actually going out there and save the world. And then once he finally gets there he never even mentions the fused name, and instead calls himself a fusion between Goku and Vegeta, making that entire scene of him thinking of a name for himself completely pointless and without payoff. Thankfully they don't go through the entire list of forms for Gogeta again, they skip the base form and the red god form, but once the blue form comes out I have no idea what is going on anymore, it's all just too chaotic and the movie just lost me.
Broly doesn't seem like a deep character. He barely even has dialogue. Once the fighting starts he has no more lines at all for the entire rest of the movie. He's either just a mute statue or a monster that just attacks everything. There's no nuance or depth there at all. When Goku visits him at the end of the movie on his planet he doesn't say anything. The green girl has to talk for him. She's a side character and she has more personality than Broly.
