I've always felt sorry for the guy.
He survived the holocaust (which most of his family didn't), just to have his beautiful pregnant movie star wife brutally murdered.
As far as his films, I've seen four, and they are all excellent. "Knife in the Water" is his best, followed closely by "Chinatown", "The Pianist", and "Rosemary's Baby".
I still need to see "The Tenant".
