Not bad for a first Nazo Movie.
Ok. Since this is like the first Nazo movie I've seen ANYWHERE, I'll give you that. But there are a couple downsides to it. First, Shadow and Sonic don't fuse (though they'd probably look something like that if they did). Second, the movie would be a bit better if it had voices.
That aside, this wasn't too bad. And people, if you don't know who Nazo is you should visit some Sonic fansites and read up on your Sonic characters because you are out of the loop.
