Great movie!!!! Anytime you get Vince Vaughn, Jason Bateman, and Jon Favreau together you know you will be entertained! Although, Jason & Jon were supporting actors in this movie, they added great humor in this "romantic" comedy! It was a very realistic depiction of how men and women think differently causing the dowfalls of relationships! The ending was perfect...not because it left you anticipating a sequel to the movie, but because again it was realistic to the posibility that sometimes too much hurt and/or damage has been done to salvage relationships. So you reflect, move on, meet again, and maybe have another chance at starting all over again. Awesome movie!
