I gotta say... that was lame.
First of all, how do you put sonic and skating together? He's Sonic, why the hell would he need a skateboard. Now outside of the chinsky, non existance plot there are a few other problems. The obstacles he skates on are just barely decent and the background is lame and you didnt even bother to make it move with him, you could have at least used a loop affect. The ground is just black, which seems like a cop out but ok and finally your use of the incredibly overused Sonic sprite is average at best. All in all I would say this is uncreative and very average. Not good and not particularly horrible. In fact it seems like I took more effort in writing this review then you did making the actual movie.
