The movie is engaging and thrilling till the last second. The story is convoluted, but still convincing. One can find similarities with some some other movies in Hollywood ( not mentioning, guess!) shot with characters locked in a big hall discussing and solving mysteries, but is a novel approach in Malayalam industry so far, and '12 th man' has done it superbly. You won't get bored at any stage. Super-engaging and edge of the seat thriller; the suspense is there till the last second of the movie.
