Assuming you've read the other reviews on this page, I'm skipping all the diatribe about that the budget was supposedly $1,000,000. Yes, for that amount of money this should have been much better. However, as a low budget, bare-bones horror film, it really wasn't nearly as bad as I expected. I have certainly seen worse films with better reviews. The story is simple, yet ambitious, and if it fails to live up to that ambition, well...better luck next time.
The editing was iffy, the acting spotty (sometimes decent, sometimes bad), but the location is visually appealing and little things made it somewhat enjoyable to watch, if only once. I won't use spoilers, but the progression of the second-to-main character is actually fairly subtle and interesting. If you watch the beginning and the end you'll see what I mean.
In sum, is this a great film? No. Is it the worst possible film ever made? No. I found it on YouTube and the comments there are much more forgiving, perhaps because they didn't read these reviews first.
