I will admit, I laughed out loud during the middle section of the movie where you are probably supposed to cry. I don't even know why I thought it was funny (I think somebody told me that, "He fucked her so hard he killed her" and that's why I laughed), I was the only person in the theater that laughed there though.
If I put myself into the mindset of trashing the movie, and getting with a group of friends (Real life or online) and trashing it live with them, then I find it entertaining. Otherwise, I just find it tedious.
