I'm Team Harvey on The Dark Knight. I was way more interested in that stuff just because that actually had a story instead of being lulzy Joker randomness (also I got sick of "Why so serious" being a meme really quickly, that definitely plays into it )
Heath Ledger dying, and maybe partially from how dark that performance was, led to people overrating it. If he was still alive, it'd probably be "the best Joker performance" instead of "one of the GOAT movie performances of all time."
At some point I'm gonna watch for the first time/rewatch most of the major comic movies so maybe my opinion will change.
