All the DBZ movies were reasonbly okay, like not a boring progression of story, but then BAM it's over with one kamehameha or something.
I liked the one when Gohan was still a youngun and kicked ass in the tournament. But yeah first Brolli movie, everythings going well, then Goku gets the super powerup, FIGHTS BROLLI FOR A WHILE, YAY. Then it's over. And then they go back and what have you. Not too bad.
