yarg! Filesize!
I know, you're going to get sick of hearing this, but here goes: filesize.
That whole intro piece was nice, but it didn't have anything to do with your movie, and it was just taken straight from the show. It probably makes up the bulk of the movie, being that the rest is made up of jpegs from dbz fansites. I do appreciate the humor, though, it's something I've thought about for a long time (even back as far as Voltron, why not just put something between the lions, huh mr smarty monster?)
Hope that was constructive, I forsee 800 "DBZ IS GAY" reviews, hope this one could be useful.
