Lousy actor in the original Star Wars trilogy and that’s about all he has ever done.
Although I am aghast that Mark Hamill is doing this, I must disagree with your statement on what he has done.
Mark Hamill is one of the preeminent voice over actors in animation and his voice overs for the Joker is the industry standard.
He really does the voice animations well and you probably have heard him in things and never knew.
The originals were the only one’s worth watching!!!!
