OK what did I watch?

I just got this out of a bargain bin at Walgreens, though it said "Exclusively at Blockbuster" on the DVD. I'm sure they bulk purchased from closed down Blockbusters. Anyway. So I come on here and every other thread people reference scenes that I never saw. What the hell am I missing? They sound at least interesting.

A wolf? Avril Lavigne stripping? I just noticed the IMDb page credits some woman for being in a gorilla costume, I never saw that!

How much is different? Is this why the R rating makes no sense? Because this movie looks more like an episode of Bones. There was nothing remotely sexual in this film, unless I suppose you like body parts. There was nothing excessively violent, no more gore than you'd see in any crime drama.
