Horror films fall into two camps for me - serious horror and not serious horror. Serious horror is focused on delivering good scares with mood, shock, etc.; it requires a highly effective director and story to pull off, and my standards are very high. The not serious horror is very different; the focus (in my opinion) is not necessarily on creating real scares through a sustained mood of dread, but more on a fun story, loose horror, typically young actors, some comic elements, etc. This movie is clearly in the latter category, and you must have that mindset going in to enjoy it. Be warned - its very low budget, and some of the acting is ok (and sometimes there's a very noticeable discomfort as an actor looks directly into a camera). But...on the good side, the dialog is generally good, there are no characters that I hate (which is often a downfall of low budget horror), some good comic parts, and its filmed on a boat, a fun thematic element to me.
