i think batman begins was simply nolan "playing it safe" the first time around. and that included keeping the name batman in the title, which i prefer. despite it being an origin story, he still kept pretty much to the batman-movie-forumla of the past films, that by the films end hes fighting a super villian in some OTT way. im not a Begins fan really, but it was defintly more a "batman" movie then the later 2. TDK was nolan doing his own thing, obviously making it more "crime thriller" then "batman movie". for many the movies only saveing grace was ledgers joker, but i failed to be impressed with his performance simply because he did not remind me of anything joker. more like some random pshyopath no different then a makeup wearing scorpio from dirty harry. people talk about burton changing penguin, but...look at nolans joker. my God. penguin is a different story. that character in the comics is boring. burton gave him interesting backstory and depth he could never have had in the comics. but what nolan did to joker was just unnessacary. why mess with perfection? just to be different from nicholson, you made joker a greasy hobo? i dunno....not what i was hopeing they would do.
anyway, TDK and TDKR were more nolans movies then it was anything really batman to me. tim burton for me, his style fits batman. nolan should have just stuck with making crime thrillers and pshycological thrillers rather then making a batman movie. anyway thats the way i feel about the whole thing.
