I had actually been wanting to watch this movie for quite some time, which may have been why after about an hour into the movie I was feeling kind of disappointed as it was quite mediocre at that stage with only a couple of bland kills, uninteresting character interactions and the suspense that they were trying to build the whole time just wasn't hitting the right buttons for me. However, the latter parts of the movie were really entertaining and reminded me somewhat of Hatchet (2006), perhaps Hatchet was partly inspired by it?

There's a couple of decent kills but they're mostly toward the end, so if you can stick it out like I did, sitting through the first hour pays off with its carnage at the end of the movie.
