Almost as good as an out-an-out action movie can be I am not a big fan of action movies. The reason is- they don't offer anything new and I always believe there's a limit to how much you can enjoy them. Beyond a certain point, they become monotonous.
Coming to Kaithi, it has got many things right which other action films usually don't. One is the fact that it does not lose the plot badly. The director is smart enough not to include any lousy action scenes, flashbacks, and pointless comedy. The action is limited and doesn't get repetitive. For an average Indian, it may look grim and goresome, but for fans of this genre, it may seem mild.
I didn't like any of the characters. They are not good enough to love but not bad enough to hate either, i.e, they lack depth. Action is not top-notch, it's just okayish. Plot-line is thin but it's not a bad thing at all. But for an action movie, 140 minutes is too much for my liking.
And now the big question is, is it worthy of 8.6/10? Well, just as much as Thadam and Ratchasan. It's high time we stop promoting mediocre films. Many Tamil/Telugu movies in the last 5 years have got ludicrously high ratings, this one is no exception. IMDB ratings have lost their relevance completely.
