Yet another AWESOME work.
I have an urge to just sound like one of those screaming fans, "OMG AWESOME DIS IS TEH BEST ZOMG YOU FREAKIN' ROCK!!!!!!!!ONEONE111"
But I respect you more than that, so how 'bout a serious review?
GRAPHICS: Not only the best sprites around, and although I preferred the Yoshi's Island Yoshi sprites and the Wario Land 4 Wario sprites, the ones you used fit much better. The custom edits were just pure awesome, and I see that it takes time and effort to customize them so well!
STYLE: DBZ owns. You finally finished, after 5 episodes, getting rid of all the backstories, so that all the action was focused here!
SOUND: I don't think I even recognized most of the music, yet they still fit so well, were great to listen too, and the sound effects rock, as always--I give that a 9,000+/10 ^^
VIOLENCE: LOVED IT. Kinda sad you took out the Koopa Bros. & Axem Rangers X, but hey, not everyone lives like Yoshi did vs. Mecha Sonic!
INTERACTIVITY: Play Button=1, Scene Select & Credits=2, Text Buttons=2, manuvering through credits=2. INTERACTIVITY=7
HUMOR: I'm gonna have to watch that again, cuz I was trying to watch Shadow & Mecha fight . . . but I was too busy laughing at the others roll down the hill! Waluigi Inner Tube=+$9,000
OVERALL: I am extremely hypercritical, but I love DBZ, and you were damn near getting straight tens (pay no attention to interactivity; it's a movie). I just liked the action more than the humor. And you STILL got a 10, and from me of all ppl. Anybody who gives this less than a 10 doesn't like more than 1 of these things: DBZ, Mario, Sonic, Flash films. I don't even know much about the world of Sonic, and I still love this! 5/5
Oh yeah, You'll hear from me about how awesome this is on DA as well; I'm the guy that drew the Super DA Buddehs Melee pic ^^
