If you're looking for a serious movie, avoid. If you're looking for a Bollywood drinking game, this is perfect.
A big chunk of it was paint-by-numbers melodrama and breaks into song at the least appropriate moments (I did enjoy the music videos, as entirely out of place as they were; 2 of 3 stars came entirely from that). I won't spoil the movie, but suffice it to say that no Bollywood tropes were harmed by the end.
The story began quite confusing and disjointed, progressed to making a little more sense by the middle, and then started falling apart completely as Neetu Chandra's increasingly laughable attempts to depict a crazy person reared their ugly head. Wide eyes are just not enough to carry a whole performance. I put a big chunk of the blame on director Jag Mundhra, who obviously made her act that way and allowed such a silly script.
I was hoping this would be one of the first genuinely gripping Indian thrillers, but it was just a series of old clichés instead.
The occasional puns on English weren't bad, though the mention of Welbutrin as a treatment for schizophrenia had me cracking up; if anything, Welbutrin would probably worsen that, it certainly isn't an anti-psychotic at all.
