Saw this Thai movie from the makers of Shutter the other day at Central:
Very interesting plot of a girl haunted by her ex-Siamese twin, who died when they had an operation to separate them. The movie had all the requisite chills, but at some points it was unnecessarily dragging, which was why I snoozed 'a bit'. The film was beautifully shot though, but the story could have threshed out the conflicts and issues of the main characters better.
Oh, and there's also a very nice twist in the end, which was a bit weird from a character development point of view. Okay cryptic... watch it!
