potential
the only thing that really kept me going was the anticipation of the fight. but you see, the thing is if you really want them to be charging up for that long you need to make the shots more interesting at least. that is if you're not going to cut them down, which i think you should definatly do. also vegeta saying "lol" from time to time took away the experience. i wasn't sure if it was supposed to be a humerous spoof, or a genuine story you were telling here. also the fight at the end was kindof lacking. take some notes from some of the other flash artists around NG. the powerstar is one that comes to mind immediatly. all you need to do is fix these things and your movie will even better then it already is!
basically you need:
more interesting angles
cut down the carge up time
unified tone
well choreographed fighting
you already have the mood and feel of the dragonball show! you got serious potential! keep up the good work!
