Bhoothakaalam (The Past) has an eerie vibe that is enough to make you uncomfortable. Starting from the opening sequence, you know there's something wrong - the house, the mother, the son - but you just can't put your finger on it. It is in this suspicion that the film weaves its subtle horror and takes you on a journey of scare. This is one of those rare Indian horror films that will scare you. Don't watch it alone.
