I respect your opinion, but have to disagree. The Joker is all those things, but he's also unpredictable so nothing is quite out of character for him one way or the other. This movie is about the man who becomes the Joker which, depending on who you talk to, is either the Clown Prince of Crime or an agent of chaos as Ledger recently made a staple trait of the character. From what we've seen so far, Phoenix checks off a few boxes, he has the look of the Joker, he has the temperament of the Joker, and he has the psychotic tendencies. He's more of the Joker than both Romero and Leto who both came toe to toe with Batman but didn't embody some of the truer elements of the Joker that you've outlined.
All I'm saying is as fans of these characters, we can't limit our view of who these characters are or what they have the potential of evolving into. Otherwise, we'll just keep getting the same iteration that'll always be compared to our own version of what we think is the objective portrayal of the character.
