This plot is quite unique. It's about manholes and I havn't seen a movie like this. Sadly the story is lacking in many ways. I missed loads of informations about characters, this movie would have been very good if they give us more detailed information. It is actually one of those easy killer movies, without a clear motive or a good story to back the bad or good guy up. Too bad. The acting was really nice. There wasn't much music involved and I might rewatch this movie because I liked the concept of manholes. I don't think this movie is gory, it is nasty but they don't show much of what is happening. Watch this if you like horror movies. Skip this if you want a good developed characters, action and a good story.
