Any film needs to have a central plot/story which would essentially form the one-liner for the film. With Kaappaan having quite a few plots like organic farming, India-Pakistan military wars, the director himself seemed confused on what the main story was. Eventually he tries to focus on all of them and they end up as half baked verbal preaches with clichéd dialogues, showing how average the writing has been.
The screenplay is even worse with a lot of scenes appearing disjoint with each other and not flowing smoothly over time. Without any great twists, after a point we all just wait for the movie to end (the sarcastic applause from the audience at the end testimony to this).
There were a few positives in the movie too. Despite bad characterisations, the performances were decent enough. The amount of research KV Anand has put into locusts and organic farming is commendable (wish he'd put in the same for the story too). Also the first half had a few adult jokes which were very much enjoyable. But in the end he wasn't able to make a quality product with all this.
On the whole, this movie would be a big disappointment if you want to witness a good action thriller.
