We were promised that Jeremiah was ACTUALLY the Joker all along so, when Jerome died, I was sad but also anxious to see what Jeremiah would bring that could possibly be better than Jerome.
So far, though Jeremiah is quite perfectly devious, he is NOT the Joker I expected. Jerome had that nailed. Jeremiah is the exact opposite of Jerome... He is calm, cool and possesses a Riddler-like level of intelligence and thoroughness in his deviousness. Oh, he's good. Very, very good. He's scary.
He is not, however, the Joker. He lacks the delusion, the pure delight of the chaos he brings to Gotham. He has a calmness I saw in Heath Ledger's Joker but, even Ledger was quite unhinged. Jeremiah is far to composed to call himself the Joker and I find myself quite disappointed.
