This has become a trend. A realistic story in a cinematic taking. There is no proper research for the film, even if it was there, it wasn't enough. Other than the lead actress others couldn't pull off the performances. The story is vague and was probably written having few scenes in mind, which in the end didn't pay off. Psychological thrillers are entertaining, but I'm afraid the south indian industry is making many psychological thrillers that we don't really have the same tension anymore as we would have in 2015 or so.
Technically, the color story of the film is good and carries the mood throughout. That's the reason I gave 1 star, if not would've been a 0 from me. Other than that, can't really appreciate other technical aspects
as camera movements were all over the place and the screenplay was no different than what we've seen in in last decade.
Overall, I feel it's too late to even say that it is a good attempt because we've seen many such films in the recent past and lacked a new element. Me stressing on being new is because the youth and the new filmmakers are the ones who can dare to make new films (mostly).
All the best to the team for the future.
