Saw it tonight ;-P I found it to be hilarious, sort of in the way that one laughs about Chuck Norris, except with Bruce Willis in this case. The shit they put him through is just plain funny. And I don't think there's a single non-bloody scene of him after like 30 minutes into the movie.
But yeah, I think the movie sucked, but that's what made it funny, so it didn't suck. (Fuck, a contradiction.)
