My only tip would be don't miss the beginning it's crucial to the film. Ayushaman Khurana is just awesome in this movie. Radhika Apte is absolutely spontaneous, funny and chill in this movie, kudos to the dialogue writer. Tabu is mesmerizing as usual and we see her play a very different role this time. Once again it has been proved that Sriram Raghvan is the king of Indian thrillers, from the beginning to the end the film makes you keep thinking what next, which is the best part about the narration of this film.
