Enevhar Aldarion
Hero
Loki starts after the first Avengers movie, but ends after Endgame, so if someone were to foolishly watch Loki before all the other movies, they would be spoiling all sorts of stuff from the other Avengers movies. Plus, we need the emotional investment in Loki from watching all his movie appearances, and especially his death, first, or the story of the variant Loki in the series is greatly diminished.
