Thriller? I didn't find this thrilling at all! Now, don't mind me! No hate towards both the actors, I love Kartik and alaya. Their performance was decent but the plot was psychotic. I mean if you are someone who is in awe of psychologically psychotic creepiness, you would enjoy it! (This statement is to define the role and character of Kartik)
A little twist-y plot with things going different could totally make this movie evergreen or something you could have enjoyed watching more than once! (Probably after a long duration, eg- Drishyam)
Instead, this plot just ends toxic! Although, deserving but still! (Personally I'd prefer something not-so-toxic or just happy 'deserving'!)
If you are looking for a review to decide if it's worth watching or not,
I'd strongly recommend search something better instead of this.
P.S- If you actually did dig this review I'd recommend 'Knives out' movie starring Chris and Ana De Armas! And, if the creators are wondering, that's a title for "Thriller", totally justifying the genre. (That's what I watched after watching this movie to reduce the disappointment)
