(By the way, A Walk Among the Tombstones is really good.)
This is a movie that I don't really know what to do with. As an extremely trashy, annoying, exploitation movie throwback, Gutterballs definitely succeeds, and almost rises beyond what it needs to do in order to live up to that reputation. Filmmaker Ryan Nicholson takes the typical rape/revenge exploitation plot, adds in the requisite over-the-top villains (the rapists, not the killer), peppers in other airhead characters to be fodder for the killer, and tops it all off with some ridiculously gory and equally exploitative kills. In a lot of ways, this setup worked for me. But there were a few things that took me out of the film's cheesy world that made me not completely love it for what it was.
Nevertheless, Gutterballs is pretty much exactly what it wanted to be. A completely crazy and kitschy exploitation film with all the sex, nudity, and gore that you could possibly stand from such a film. It's got real boobs, fake penises, buckets of blood, and according to Wikipedia, 625 uses of the word "fuck." Break out the popcorn and indulge in something truly trashy for your next movie night. And be prepared for Gutterballs 2: Balls Deep, which I believe they are currently working on!
