Scott McClure does great work but it's also still his unique way of it, I love his Joker for what it is. The whole Joker Blogs series really pulled me in and held my attention, highly entertaining to watch and the story unfolded awesomely.
Wow, not bad! That's a hard laugh to imitate though. I imagine Ledger had to practice it a lot.
