'Mom' was easily a great leap for the career of Sridevi, who played a killer with originality and a mother with much-needed vulnerability. But the script sags a lot and there's not much believability in the screenplay, a stage has been set for most of the problems.
The problem is that despite you are hooked to the screens thanks to its actress and an engaging plot premise, you'd never feel her reasons: and that's largely because the film has an inconsistent tonality, and waferthin ideas are camped upon by the filmmakers about the briskness of a thriller.
