I'll freely admit that I, along with a few friends, went to see Pathology because we'd heard that Milo Ventimiglia was nekkid in a few scenes. I'm shallow, but not so shallow that I can't admit that I'm shallow.
If not for the aforementioned shallowness, I don't think this is the kind of movie I would usually see. So imagine my surprise when I actually liked it. Yes, it's extremely gory and twisted, but there's something fun in all that. The cast clearly had a blast with their roles, it's easy to imagine outtakes with the actors playing around with some of the more disgusting props.
If you don't take the movie too seriously, it's actually quite enjoyable, and even at times rather thought-provoking. As we left the theater, a discussion was struck up about who we would kill if we could get away with it. All in jest, obviously. (A popular answer "Whatever genius was in charge of marketing this movie." It's only playing on about 45 screens in the entire country.)
Admittedly, this is one of those movies where you're either going to love it or hate it, no middle ground. It all depends on what you're into, really.
And on one final shallow note, if you're a Milo Ventimiglia fan, let's just say you won't be disappointed.
