Yes, it's not about being negative, it's about Steve sounding a bit more "right" to us. Jerry is a great performer and if he had done Statler on the Muppet Show it would be fine. But many people got use to Richard's Statler and when Jerry took him back it was like a huge shock to the system. When Steve took over Kermit, he sounded like Kermit. When Eric took over Fozzie, he sounded like Fozzie. Jerry just doesn't sound like the Statler we know and that's not being negative, it's being truthful. Richard's voices are just too darn hard to get right.
About Dr. Teeth, I haven't heard him enough to make a judgement. I mean, I'm sure anyone can do one word really well.
But to really get the character is different. I'd like to see more of Dr. Teeth and maybe get him back into the shows and movies more.
One thing I loved about AVMMC was that it brought back many characters. Not just Scooter and Janice, but Kermit, Piggy, and Fozzie as well. They hadn't been very in character before AVMMC. Kermit has to be sarcastic sometimes and he has to get all frazzled because that's Kermit! He's not always nice. Steve can actually do a good Kermit if he's given the right script.
When the new muppet show comes out we should see the same kind of mix we saw in AVMMC. Jonny and Sal should be in there, but not as main characters like on MT. Pepe should be a secondary character like Gonzo was and he and Rizzo should be paired up more for certain things that involve sneakiness.
Fozzie and Piggy should be and can be main characters along with onzo and Kermit. We should also bring back the Electric Mayhem. MT wasn't the muppet show so I see why the EM wasn't used there, but if this new show is suppose to use the classic characters again, then it should use the classic band.
One last thing. Bring back Clifford! But don't bring back MT Clifford. Bring back the cool hip Clifford from the JHH and MFS. I loved that Clifford! And bring back Leon too! I only saw him on that Cosby special but he looked like a cool character and had a great voice. Kevin is really talented and if they bring back those two characters and Kevin still does Sam, you have 3 characters for him to do as well as bvack ground stuff. I think that's enough to justify hiring him full time.
