How this movie got good reviews, I will never know. And how people got tricked into liking this movie, is mind boggling. Just a note, I really liked Get Him to The Greek & I Love You Man, so I usually enjoy this realm of comedy. But the comedy in this movie is weak and falls flat. In hindsight, I try to think of one funny moment in this movie and I honestly can't. Well then; the story line must be good and/or entertaining... nope, not at all. The 2 main characters are undeveloped and unlikeable as well. The main character Peter (Jason Segel) is really good in I love you man, so it was obviously the directer and the story line that sucked. Mila Kunis (Rachel) has some like-ability. I also like the Aldous Snow character, but that can't even come close to making up for this pathetic excuse for a movie. It's not only humorless, but approx 3/4 of this movie are uncomfortable to watch and at no point are they situations that are uncomfortable in a funny way. I don't always dock a movie because of predictability, but from the moment Peter get's to his vacation destination, you know exactly how this movie will play out. Some things in life are unexplainable; for example, the Pyramids and how people got tricked into liking this movie. It's uncompromisable & mind boggling! As badly as I would like to rate this movie a 1 out of 10. I will give it an honest rating, which is a 3 out of 10.
