If you have no past experience of committing suicide, then here's a tip: that thing is best kept short, and if you've done a good job, at the end of 120 minutes your body should be merrily decomposing, not spasming about on a respirator. But why do we bring that up here, you ask? Oh, nothing - just a random thought.
Anyway, Khaidi Brothers is a story of two dumb brothers (as in "cannot speak", but it's okay) who take revenge on some rudimentary villains. Noting the inadequacy of either brother to be either the hero or the heroine, the filmmakers bring those in too, in the form of Saikum....
