I hope Seth Rogen watches himself in “50/50” (2011) and vows only to be like that in every movie he ever makes for the rest of his life. Supporting actor. Saying stuff that makes me laugh out loud five minutes into the movie. Pulling me back when the friend-has-cancer stuff gets to movie-of-the-weeky. Smoking pot in a way that is appropriate to the plot and not just a lazy comic crutch. What a pleasant surprise. Joseph Gordon-Levitt was the perfect straight man. Kudos to Bryce Dallas Howard and Anna Kendrick for making chicken salad out of their chickenshit, one-dimensional characters.
