Cinema mind trickery at its best. The execution of this film is phenomenal. The acting is topped by an always impressive Leonardo DiCaprio, reliable and understated Mark Ruffalo, and Ben Kingsley at his creepy best. The scene with Patricia Clarkson will have you wishing her an Oscar for the rest of the week. The methodical slow pace for the movie works eerily perfect. The movie won't quit on you even after you are gone from the theatre. You will be up for nights second guessing yourself and the movie. It gets you thinking, and hard. It's cinema mind trickery at its best.
