Except for that revolting bathroom joke,it was very funny. I watched it because I'm a Chris Rock fan.James Marsden was hilarious. Dude was too convincing as a man whose mind was touring the outer planets.
I actually laughed loud enough that my neighbors outside were looking at my upstairs window like "WTF"
Chris Rock was great, and in a different sort of way than usual. The Danny Glover/Tracy Morgan bathroom scene had me tearing up with laughter and disgust.
