So I checked this out last night since it would be the last showing of it in theaters.
Thoughts:
Not even acknowledging red-hair SSG and going straight to SSGSS was very strange. They also avoided calling it SSGSS in the English dub, but there was a goofy "naming" scene for Golden Frieza which would have worked better if Goku had named it SSGSS and had Frieza point out how redundant that sounds.
Master Roshi's commentary during the fight was great. Everyone else's was lame catchphrases. Z warriors fighting a bunch of faceless nameless goons for 15 minutes isn't very exciting.
The fight with Frieza was kind of boring because there was only a few scenes with actual choreography, a large chunk was 'ooh look they're moving so imperceptibly fast' sonic boom stuff all over the sky, only pausing to acknowledge how uneven the matchup is. "Hmm-hmm! You're stronger than I thought!"
I'd say the movie was a little more serious than Battle of Gods, but ultimately seems to fall into the skippable, throwaway category that most anime movies fall into, with the small caveat that this will be rehashed through DBS, but with shittier animation.
Maximum the Hormone's "F" seemed muted and low-quality both times it was played, I don't know if that's the fault of the dub or what. The second time it played there were no lyrics. For being the inspiration behind the creation of the movie, they really didn't do it much justice.
