Some snazzy shot-taking—like the opening images of spooky cupboards, fridge and washing machine—and an interesting premise of how a TV serial can take over our lives makes 13B a sufficiently good scare. At the centre of action stands Madhavan, who invests in a flat along with his brother, and the entire joint family moves in. But things don’t seem to be all hunky dory. Milk keeps curdling, photos of gods can’t be hung on the pooja wall because nails refuse to get drilled, the lift decides to have a mind of its own every time Madhavan tries to use it, the neighbour’s dog is too scared to enter the house and the pictures of Madhavan taken on the mobile come out all twisted. Things come to a head when the favourite serial of the family starts pre-empting events in their own life. It’s for Madhavan then to go back in time and resolve the case of family killings and a suicide that happened in 1977. It also makes the filmmaker take us on a nostalgia trip to early B/W DD days when television were like wooden boxes and Telerad and Televista were the in brands.
