SKETCH is clearly a watchable action thriller. While its lead star Vikram, the plot twists and the action sequences dazzle, the romantic subplot and the not-so-great songs hinder and at times even irritate. Still, SKETCH is watchable, because the way the climax changes the entire game for the film needs to be seen.
I thought I wasn't going to have a very great time finishing the movie, I was taken by surprise, by the entire climax episode. I really loved all the action scenes, Vikram's performance, and the common usage of "slow motion" during the action, apart from the entire interval sequence. I also loved how the director brought up themes of friendship into the plot but also got disappointed by the way the unwanted romantic subplot was inserted, undoubtedly, as a commercial compromise.
Except the very first song, I didn't like any other much and even skipped most of them. While the first half is saved only by Vikram, the action and the interval episode, the second half, which raises expectations as we all know the basic storyline, turns the viewer down when songs start to pop out of nowhere. SKETCH deviates, and seriously without these songs and romance, it would have been an extraordinary action thriller.
Some more "sketching" was needed and it would have really turned SKETCH into a masterpiece.
