It's not bad all round...and definitely kept me watching. It has some creepy moments that made my hair stand on end, and a jump scare or 2 to keep you on your toes. Most of the creepy atmosphere is down to the clever use of sound and music and some crafty editing. Solid performances from the entire cast, resulting in a believable family unit placed in turmoil due to ghostly goings on. It does loose its way towards the end, and I was a little disappointed in the direction it took.
The main idea of the film, and the context in which the supernatural element is delivered, still remains unique, and for that I did enjoy it. I was just hoping for a little more substance in the final act, and the film lost its impact for me due to the "reveal" in the final half hour. It has obviously gained some notoriety due to a sequel out this week, and I hope the continuation of the story will shed some new light, and possibly redeem its predecessor...
And now here I am, fairly disappointed, with dry underwear.
Under the cold light of day the reveals are a bit anti-climactic, leaving you thinking "Really?" because it isn't as unsettling as what has gone before.
Having said all that, the spooky bit *DO* hold up well with the revisits, and I would say that it's definitely worth a look for genre fans.
