Being an ardent movie buff as well as a Netflix buff, I would say this is a close copy of a Spanish movie called 'The Invisible Guest'.
But if you haven't watched that movie, then this would be an awesome thriller.
Adivi Sesh does justification to his role.
Regina Cassandra was pleasant to watch.
Book your tickets, grab a bowl of popcorn, and a glass of coke, and enjoy this ride coz you're gonna love it :)
