Oh god....
I have to say, although Mike and Kevin fought the good fight on this one, the movie was just excruciating. We had to stop watching halfway through, the movie is horrible. It doesn't even PRETEND to be realistic about anything, logic, physics, biology, sociology and math alike, all thrown out the window.
It was a movie with so much obviously wrong with it that, to my mind, any jokes other than "Dear god did that just HAPPEN?" feel kind of shallow. It does not speak well of those distant, dark masters of Hollywood that a film like this could get made.
