This is no offence to you, but surely Kermit is not meant to be hesitant to deliver a line, or constantly jerk about while he's not talking - and even completely miss at one point what his co-star (Gaga) is doing to him and look blindly ahead. I mean you may not see Steve as "Kermit" but you can't say he has ever been that flawed puppetry wise.
I don't see how you find that impressive, unless you like bad puppetry. If they wanted to throw someone else in as Kermit they should at least have kept them off screen until they learned the character, though saying that, the auditions were three years ago.
I admit the puppetry seemed a bit beginner, yes. And no I do not like bad puppetry, thank you.
And Steve's early Kermit did have some flaws at the beginning; it grew over time. I won't mention specifics. I won't tear apart people's performances, like others are kind of doing here now with this "new" Kermit. (And Steve is obviously a great puppeter. He was just new to Kermit at the time).
It's not a crime to be a beginner and make some early mistakes.
I think what it comes down to is, if this was replacing Jim's Kermit, I probably
would mind. But as far as I'm concerned, Kermit's performer was already gone. So I guess that's why I'm not that upset about another recast.
