On the one hand, I am very excited that this show is getting new episodes. The trailer doesn't reveal anything significant. I'm indifferent about Mokey's slight redesign and would like to know the rationale behind it before I pass any judgment. My understanding is that having loose "frilly" hair gives a muppet more "activity & expression" when they move around and her new hair is held back and has lost that level of expressiveness that her original hair style had. Red's voice is also a bit different and I'm not sure if that's just due to the voice actress. Again, I'm not going to pass judgment until I learn more about it.
Overall, I'm excited but I don't have Apple+ nor am I going to be getting Apple+ just to watch the Fraggle Rock series. Good luck to them and I hope that the series is eventually on a more accessible platform.
