Boy, that ending was seriously disturbing. It was set up beautifully, though. The dream sequence, where it's like he was looking through a thin sheet, mirrored the shots through the shower curtain. And the shot of the clean toilet bowl filling with blood from the tank after he flushed it... A perfect, agonizing pace. Heck, I'm still not sure what really happened versus what he imagined. Hackman played the tortured soul as well as I've seen it, allowing Coppola to merge the real and nightmare worlds seamlessly.
