It was Ok (Not scary). It made me laugh in few scenes.
They had strong story (I actually love the idea of you all adding indian devil with zombies) but could have done better with the direction and could have added better scares. You had good actors they could have been used better.
Take an example of world war Z or walking dead - How zombies are made to act (walk and thier expression).
I would give 5 out of 10 for a good attempt.
