I thought the cinematography and music were fantastic, you can feel the isolation through these two elements alone, and just how eerie isolation can be. I thought the acting was pretty solid as well, but I share some of the sentiments of others in that there are a lot of confusing plot points and inexplicable random inclusions that didn't really add much if anything to the storyline ... perhaps that was the intention - a commentary on the confusion, fear, and paranoia one might feel under such unusual and unsettling circumstances. I was disappointed with how the "end" happened, not because everyone died but because they built up to the climax for a solid hour and a half I felt they devoted too little time to the ending. Overall, it was ok. I wouldn't watch it again, but I didn't HATE it.
