Forgetting Sarah Marshall is a great movie with excellent acting, dialogue and a mixture of both crude and subtle humor. The movie for me was much better than such comedies as "The 40 Year old Virgin" and "The Wedding Crashers". The characters are well developed and the plot is very "smooth". There are lot of sex jokes but the comedy is smart and sophisticated. There's a wit in Segel's writing that I would never have guessed and my respect for him has increased after watching this movie, both as a writer and as a actor. Aldous Snow is hilarious in the movie and I hope he makes more of such movies,

All in all, a must watch movie.
