They both played the character, comparisons are bound to pop up, even if their interpretations of the character are very different. I fail to see what's difficult to understand about this.Perhaps that says something about Hamill's performance, then?

Or it could just be that some people like the comparisons to be strictly between live action actors, although I personally don't see anything wrong with throwing Hamill into the mix.Not the entire movie, but we've seen enough footage by now to gauge what kind of performance he's going to give, and we know enough about the plot to know how his Joker behaves. And this isn't even going into Heath getting unanimous praise from the movie reviewers.Adam West's Batman was also paramount to the success and revitalization of the character, but that doesn't change the fact that many batfans loathe that interpretation of the character. And just because people dislike Jack's take on the Joker doesn't mean that they dislike the man himself. People
are free to dislike Nicholson's Joker just as much as you're free to lavish praise upon him. Personally, I've seen Jack give numerous performances that I thought were better than his Joker performance by leaps and bounds.Then you must not have been present when Heath was announced to play the Joker. Those comments were
flying at that time, as I recall.And I haven't seen the kind of blind bashing of Jack's Joker (i.e. 'Jack's Joker is fat! Hur hur hur!') to warrant the kind of backlash of a post you're giving here. There was a little bit of playful jabbing at Jack's imagined jealousy of this take, followed by a few brief bits of legitimate criticism. And as I've pointed out, people are just as free to dislike his take as you are to like it, so there's no need to get your knickers in a bunch.
