I'm a huge Adam Sandler fan, but this is the second in a row that has left me cold. I think this would have been funnier if Sandler had played the title character straight, rather than going for the cheap laughs. Typical potty humor, but unfortunately Sandler is getting a little too old to bring it off. There were some really good laughs toward the end, but not enough to make me want to see this again.
I loved this movie! Robert Downey, Jr. is perfect as Stark, and Jeff Bridges is having way too much fun playing the bad guy. Even Gwyneth Paltrow shows some warmth. I can't give this a 5 because it just isn't the best movie ever, but I would recommend that you see this movie. In the theatre - don't wait for video!
