Based on the trailers, I don't see how it could possibly be good, but I've been surprised before... interested to read what people will have to say.
And Mike, will you be obviously visible in the movie? I know a few people who've done extra work. Most is "guy walking across the screen in this scene stuff," but one guy I know actually had a fairly long stint of real face-time as a cab driver in a movie that was a major (i.e: out in theatres, not straight-to-video) release. Damned if I can remember what it was, though. It was a really crappy movie.
