Finally saw this. I generally agree with most of what's been said. It's fun, but not as good as Battle of Gods, and feels kinda empty. Battle of Gods felt like it was head-and-shoulders above the typical DBZ movie by having a plot, and one that was unique and introduced some new, colorful characters. This sorta feels like a typical DBZ movie. Villain shows up, minor heroes easily dispatch his cronies, but he easily dispatches those minor heroes until Goku shows up, fight, roll credits. It's probably the best-ish version of that typical DBZ-movie formula, but it severely lacks in crafting a movie and a story unto itself. I didn't have a huge problem with the ending as a Vegeta fan, I thought it was still funny, but I didn't like that he's basically sidelined for most of the running time, just watching and not doing much.
The music sucks, also. Reminded me of a lot of the crappy dubs of the DBZ movies that used crappy nu-metal songs.
It's enjoyable, but while Battle of Gods had me SUPER excited about the prospect of furthering the DBZ storyline, this has me back on the "if it continues, cool, if not, cool" side. 3.5/5
