The funniest thing about this movie might be how the advertising campaign, which includes posters and billboards that read "You Suck, Sarah Marshall" and "My Mother Always Hated You, Sarah Marshall," has made life for the real Sarah Marshalls of the world difficult. Some of them have struck back with "You Suck, Judd Apatow" signs.
While I'm no Sarah Marshall, I concur with them: most of the Judd Apatow movies do suck. Check out the films he's produced and directed. Hilarious fare like 40 Year Old Virgin, Knocked Up, Walk Hard, Superbad, Talladega Nights, etc. Ugh. Apatow has earned my ever lasting love for Freaks and Geeks but he (and his progeny) have clearly gone for raunch over nuance.
I'm really glad Jason Segel and Seth Rogen have been able to get ahead in life but really, they're not good enough to be leading men. If not for the adorable Mila Kunis -- and Russell Brand (as Aldous Snow) -- this movie would have been a total waste of time. The entire thing is uneven and swings wildly from sometimes amusing set piece to totally off the wall unfunny set piece.
James (Okapix) has this theory that anything over 90% on Rotten Tomatoes is worth watching. His thinking is that if a wide majority of critics and viewers like something it must be good. But I tell him repeatedly that anything the masses like is actually much more likely to be terrible. This film is a perfect example of that. 85% on RT and great reviews from most of the critics.
Skip it and forget it, seriously.
