The reason why movies generally from Indian subcontinent are super long is because of unnecessary long comedic exchange between characters which amounts to nothing in the story, Item dance (Sensual) which doesn't offer anything to the plot.

Even if its a serious movie and the story is going in a flow its disturbed by things like this.

Kaithi excels in these departments, it had one goal and no distractions.

Personally I think stories which are completed within 24 hours are the best.

After reading the synopsis I thought there will be a past to the Main male lead which is almost repetitively similar to every other movie with anti-heroes. But was surprised when Kaithi delivered the backstory in just under a minute without dragging the story.

Overall not a single moment in the movie felt unnecessary at least to me.
