I personally would rank the movies TDK>BB>TDKR. Maybe BB and TDKR are about the same, I dunno. Full disclosure: the Batmen/Xmen comics were what I primarily read as a kid, so I've always had a soft spot for the film adaptations. Especially since the whole Bane/Azrael arc happened during my last two years of high school.
And yeah, I'm totally and unabashedly on Team Grimdark, and no fucks are given. I know lots of other people like comics for different reasons and enjoy reading lighthearted blah blah blah whatever, but I never got into that. Yes, I watched the 60's Batman tv series as a kid and enjoyed it, but didn't love it. I like comedy and shit like that fine, but not with my superheroes, kthxplzbye.
