I was just thinking it should have been a 9 or 10 ep series, and Marvel has such a poor track record with that, but honestly they pick the worst projects to turn into series. She-Hulk was rushed, padded, and edited badly, one character with one joke - but in Eternals here’s a chance to have a full 50 minute prestige episode about Kingo and his whole thing so we actually understand him and they’re like nah, a line of throwaway dialog is fine.

All they had to do was write five eps: Thena/Gilgamesh, Kingo, Phastos, Sersi/Ikaris, and maybe Sprite. One ep intro, a couple main story eps, and the two-part finale. No movie, just put that effort and financing into the proper format for this sprawling new universe.
