This pretty much brought the super cheese and I think Jaleel sounded awful as sonic, I think we're all pretty much past that voice at this point, even if it didn't even sound remotely like his old school voice.
It was a decent experiment, I wouldn't back such a movie though, I enjoyed their megaman one, and I'm still waiting for a real dragonball z movie to happen, even if it's fan made, someone has to have the brains to create such a movie.
