Very surprised!
I found myself laughing out loud through much of this movie. Yes, it's predictable...yes, it's a corny, romantic comedy...and no, I don't care if it was just like some other movie. From the perspecitive of sheer entertainment, my wife and I had a great time at this film. JT surprised me...I thought he and Mila Kunis had great chemistry onscreen. And Woody Harrellson just cracked me up in every scene he was in.
Word of warning though. I was surprised that some people were bringing their younger children to the movie. Let's just say this movie has very "adult themes". If you don't want to have to try and explain the finer points of oral sex to your 11 year old...I would suggest leaving them at home! ;)
