Initially I thought of the usual bla-bla which an Indian guy excepts to be there in any horror movie but moving on with the flow of the movie one is left clueless..Great thing about 13/B is that the viewer can never become a predictor of the twist..Such movie should be appreciated but unfortunately it's an underrated one..R Madhavan is fav as always but other characters are also good..The movie is more of a suspense-thriller kind than horror-thriller..Its totally a new concept which is worth watching ❤️
