Seth Rogen -- Another one-note actor
Admittedly I used to love the movies he was in such as, 40 Year Old Virgin, Neighbours, Knocked Up, This is the End, Superbad, The Interview, The Night Before and so on. I suppose I've grown tired of his one-dimensional characters as I've seen what he's capable as an actor... not that much (act as a jerk, smoke weed and vice-versa).
If you like him and his one-sided characters there's nothing wrong with it. Everyone's got their taste.
