My favorite scene is that throughout the movie you can see both Pi and Richard Parker losing weight which makes the scenes more believable.
Pi finds Richard to be intimidating and hostile. He tries to tame him. Richard, as most of the cats family, thinks of Pi as just a provider and goes back to him only when he needs food or to be pampered. They both try to show that they got the upper hand and power.
Pi’s story is interesting, but it is not realistic. Moreover, it doesn’t answer the writer’s request which is “make me believe in god”.
