Gritty realism isn't always the best route to go, though. More realistic seems to be a general rule for better comic book films, but the Joker should still have some pinache, you know?
I expected it to be a little more........enthusiastic? Hamill's Joker sounded like he was really having fun and laughing for a purpose, whereas so far, it sounds like Ledger's Joker isn't going to be fun at all, you know? Like they've been saying, "its more about his eyes than his laugh"...but really, we all know its the laugh that solidifies this character.
I'm not going to completely throw it out the window yet, because originally I hated the design of the Tumbler but I grew to like it a lot, so I'm hoping its one of those situations. I just hope that that was the worst we get and that everything from here on in is a better Joker, and I'm hoping that the appearance of the Joker so far that we've seen is only pre-acid lol.
