pretty cool...
but, when you say that it has nothing to do with DBZ... you can not get mad if, after seeing your movie (trailer?), people assume that it is taken from the Dragon Ball series. After all, it does have many similarities. And yes, of course abilities such as throwing energy, flying, etc. are not limited to DB/DBZ/DBGT. BUT, it is, probably, the most well known (bad grammar? oh well), in north america, show that heavily relies on those aspects. Also, the STYLE reminded me of the DB series. Not the fact that they threw energy, but the WAY they threw energy, etc.
I cannot explain myself any better than that. The style itself reminded me, somewhat, of DB. But, nonetheless, I still understand that it is an original work, and I commend you on that. It is a pretty good movie. I didn't really enjoy it too much... but that's just me. I assume that was a trailer, and not a full movie? Just an assumption...
