The therapy scenes ring true and the movie has its funny moments, (show me a guy that can't relate to the tissue scene), but like others have said, almost all of the funny moments you've already seen if you've watched the trailers.
In fact, if you're looking for action, this is not the movie for you. It portends to be a sensitive & thoughtful romantic comedy designed to display obvious faults and their climactic resolution.
My wife and I were the only ones remaining at the end of credits. I'm surprised that no other reviewers have mentioned that there is a pretty funny clip at the very end of the movie after all the credits have rolled that every guy will be able to relate to.
