I went to the world premiere for this film last night and found it thoroughly enjoyable. Obviously, it's a small movie, but the dialogue is great and it looks just like a bigger budget film. Of course, the actors aren't Robert Deniro, but they really hold their own. I would strongly recommend this film to anyone who likes great dialogue and funny characters. Just be ready to accept the fact that the film is full of unknown actors (though I gotta think that the guy who plays "Kevin" won't be for long) and is quite "raw" at times. However, if you only like big studio movies with big budgets and big actors (so you hated stuff like Clerks, Mallrats, Ed's Next Move, etc.), you might be better off seeing something else.
