Ek Tera Sath is a horror movie with a regular story not very much interesting and in the movie the characters are also not as much fitted for acting.
The dangerous and piculiar scene is that when the Aditya’s ( the main actor of the flim) wife dies and after many years police came for investigation but he runs out scaring from the paranormal activities saw by him.
I dont know why this character is required if you adopt a lady tantrik for this purpose and the most funny thing is that the owner of the palace fall in love with her.
I want to say overall it is not a bad or good movie.
