Marvel’s habit of poaching talented young writer-directors for their films has gone from something largely positive (cultivating diverse up-and-coming artists) to something seen as negative (wasting years of the lives of potential new auteurs on paint-by-the-numbers franchise filmmaking). Taika Waititi was an early example of this—Thor: Ragnarok was widely praised, but Thor: Love & Thunder was far less critically acclaimed, and now Waititi is very willing to let the studio move on without him. In fact, he never meant to get involved with Marvel at all.
