This show is so damn good. The writing is amazing, visuals are stunning, acting is top notch (confident David was almost as unnerving in his own way as shook & scared David playing Rainbow Connection was, and Aubrey Plaza is killing it), and the music fits perfectly.
It's so great how they plucked out and completely re-imagined the concept of this mutant character to examine and play with visualizing mental powers & mental illness in television the same way Claremont & Sienkiewicz used the comics medium to explore the same subject matter by having the New Mutants running around in David's mindscape. It's so on point to the spirit and intent of the original story while being totally and completely its own thing.
Was gonna make a post but this one sums it up well, well said.
This show is so disorienting in all the right ways
