This is almost a new genre and a proof that old fashioned horror isnt scary anymore (except for kids may be).. well written story which has some thrills, chills and scary moments.
From the best directors in Indian movie industry (bollywood) comes ghost stories.. 4 short stories which are scary even though they have no real apparitions..
This is a testimony to the fact that bollywood which is known for song and dance sequences can create quality stuff. Worth watching.
