I must say, I was expecting a lot worse from this film. The whole first half is genuinely scary. Although the brother and sister's rivalry was played up just a bit too much, their characters were still a lot more believable than most modern scare films. Their dialogue was especially natural, and didn't contain a single "oh my god, like, did I just totally see, like, an undead demon, or is it just me?" which I praise the writers for (there's only so many times Buffy the Vampire Slayer can say lines like that before I start doing a little slaying of my own). Despite the constant squabbling the kids do, you can still warm up to them enough to feel empathic about their plight. The cinematography was excellent, my favourite scene being the long pan up the side of the church. The music and sound were cued perfectly and conveyed a true sense of fear, anxiety and isolation.

Unfortunately, the second half of the movie really suffers. Like so many other movies, once the killer/monster is revealed the whole thing goes down hill. It goes from relying on X-files-like suspense to bland gore and a cliché monster suit. Top it off with some overacting "we're not taking any crap" police officers and a poorly acted psychic lady and you turn what could have been a gem of a scary movie into a second rate dud. The biggest disappointment was the end. It was horribly tacked on in a desperate attempt at being a shocker.

Other then the whole second half, the only other complaint I have is regarding the DVD. The menus show clips from the movie which essentially run in sequence, and if you pay attention to them, they spoil just about everything. Where they are, what the monster looks like, etc. I haven't bothered to watch the menus all the way through but with any luck they spoil the ending too (but that's not really so bad in this case).

While the movie has a few glaringly laughable scenes of characters reacting stupidly (particularly the main actress), it gets off to a great start right away and a consistent feeling of dread, catalyzed by curiosity, which keeps you immersed. Justin Long is excellent in a serious role despite my preference of him being funny, though there is some of that, too. In fact the bits of satire here and there must be appreciated. Certain realisms such as how Justin's character reacts to a horrifying scene in the beginning was depicted really well and laudable especially in the face of other situations portrayed terribly. Effects were pretty good, albeit a bit cringe at times, but the low budget and gritty feel to the flick definitely added an unease to its horror vibe. Moreover, the creativity; this isn't a slasher flick, but a hybrid sort of creature feature. The ending, I really gotta give props for - unexpected, and it made me like it even more. I'd have given it a 7 before the ending.
