Re: What Nolan does poorest. Villain Endings
I feel that Two-Face and Bane had the best endings. I didn't care much about Ra's and Scarecrow's. Talia's was just kind of there. Joker's would've been great if we got a definitive line in TDKR about him being in federal custody, or accidentally shot after being taken into custody.
I don't think being shot in the chest with a canon is a bad death, and the whole scene was a good way to show the ethical differences between Catwoman and Batman. Two-Face's was the perfect end to a tragedy.
