Hot Tub Time Machine (2010)

So many of you have already seen this, what's the point? I thought it was a wee bit overrated. It was mildly amusing, I laughed twice. Now that I think of it, two laughs is pretty good. Even if a movie is quite funny I don't find myself laughing out loud too much. It took nearly an hour for John Cusack to register ANY emotion (besides fatigue) on his face. What the fuck is wrong with him?
