Decent watch, might watch again, but hard to recommend.
Don't get me wrong, I like the movie: it's well casted, has a decent story and production value, but even at the time of release, it wasn't great.
There are some really funny moments, and if I were Jason Lee, I think I would have some trouble choosing between Selma Blair and Julia Stiles too, but it's mostly "what awful things can we do to him" humor. Ants under a magnifying glass just aren't all that satisfying.
The upside is that there are some very cleverly crafted characters and acting even beyond that.
