Watched both of these after I got a taste for them from the Joker. Ofc seen these before.
So so different Jokers they present to us. Their backstory: first (Nicholson) was a career criminal before his change, the second (Ledger) has an unknown past with very unreliable stories about it ("do you wanna know how did I get these scars?"), and the third (Phoenix)is an unfortunate bloke with kinda mystery past due to his and his mom's mental illness. Their behaviour: a confident happy fool, an impulsive anarchist, and a confused amateur. The motivation of their followers: criminals from the already existing structure of the mob, ragtag outlaws from petty thugs to loonies, average joes who are got enough of the system. Their arch-nemeses: lonely Batman, Batman his sidekicks and law enforcement heroes, a talk-show comedian.
I think I prefer The Dark Knight, the Batman is just too wacky, and - frankly - dated, the the Joker is too depressing. And the Ledger Joker is so sinister, unpredictable, and just has fun scenes. Also that violin-ish sound effect in the background matters a lot.
