Hated it. It was kind of funny, but it was a total guy's T&A type movie. Luke Wilson will always be adorable. I can't imagine Uma Thurman playing such a dimwit in a movie, but let's be honest here, it wasn't her typical role. I really like Uma and this just wasn't her.
I guess if you're excited by tacky sex scenes then you might enjoy it. I found the movie a little over the top. Perhaps that's the point.
