Some scary moments but silly story

Rating: 6/10 (1 December 2013)

Annabel (Jessica Chastain) and Lucas (Nikolaj Coaster-Waldau) are to bring up two little girls that have spent five years alone in the woods. They're Lucas' nieces and were left there by Lucas' brother. They try to help the girls recover...but don't realize that the girls had help surviving for all those years with a creature they call "mama" and "mama" is not going to give up her children without a fight.
It's well-done, the acting is good and there are a number of places where you're guaranteed to jump...but I found this unsatisfying. I found the revelation of what the mama is pretty silly and the back story got very confusing towards the end. I found the ending wildly overdone too. Still it DID scare me a few times and it had a very creepy atmosphere so it's OK.
