Alright, here's my issues with the film
-Forced/odd dialogue. Stuff like Paragus' explanation for Broly's Oozaru power, Goku telling Broly he doesn't have to fight (LMFAO ok Kakarot), ect.
-Uneven pacing. Ex. The first half of the movie possible going a little too slow with things, while the second half of the movie going a little too fast. The forming of Gogeta and the ending resolution between Broly/Goku in particular as far as the too fast stuff.
-Hard to get too invested in the stakes because of these previous 2 issues, the nature of Dragon Ball, and the nature of it's movies.
So pretty much, standard Dragon Ball movie complaints. As fun as even the Super movies have been, I've always been of the mindset that Dragon Ball stories just have a hard time being crammed into a movie format. At this point I'm kind of aware of that and have kind of a "take what I can get" view on them.
And as far as taking what I can get, this movie fucking delivered. All and all, it's most likely my favorite of the movies, with Battle of the Gods a fairly close 2nd. I loved the meat they gave us with the first half story stuff, even if it was slow at times, and the action was about the most heart pumping that Dragon Ball has ever seen.
That being said, I would love a retelling in series form, similar to BoG and RF, because I did want more here to be expanded. However, because the animation was just so spectacular and distinct in this movie, I'm worried a series retread would run into a problem of just not being able to live up to that. BoG and RF didn't have do deal with that as much, even with the bad animation that DBS's re-tellings provided us with, it was manageable. Re-telling Broly like that would be a huge disservice.
Oh and also, while the music was generally fucking amazing, the "GOGETA!/BROLY!" chants and shit, I can't tell if they were a little too much, or just fucking perfect lol.
