Craig doesn't deserve what he got

I agree that what happens to him feels sad and cruel, but in terms of justice, one could argue that he gets exactly what he deserves because he was okay with dooming John Malkovich to the same fate. When he let go of Malkovich, it wasn't for any insight or regret for what he was doing to him. The only difference is that Malkovich was incarcerated in his own body. I'm not sure whether that makes it any better or worse.

Locking his wife in a cage while forcing her to set up sex dates for him notwithstanding.

This movie is just full of douchebags. The nicest person in it must be the chimpanzee.

Craig deserved everything he got. He was a married man who went out of his way to bed another woman (Maxine), used another human's vessel to bed said woman, happily screws over his wife cause she pretty much got the woman he wanted, is a wimpish selfish arrogant man. He was even at a point willing to let his pregnant wife die to stay in the body of Malkovich. Sure Maxine is flawed but at least by the end she redeemed herself and

Craig deserved what he got.
