Not quite to that extent, no. But we are dealing with a small sample size with SW so its hard to compare.I mean, they have 5 movies. You have 1 director gone during the writing process, and 2 after initial cuts if I remember correctly (assuming you count Rogue One in that kind of boat). Admittedly I didn't really get into the Marvel movies until a year and a half ago, but did Marvel really replace 60% of their directors? Honestly I don't know movie things all that well, so I'll ask this here as well. Shouldn't she have known the directions they wanted to take things before hiring them? Or at least before completing filming?
I mean, I'm sure I'm lumped into hating Star Wars movies. But just listen to the people involved talk. Direct from JJ: "But without getting in the weeds on episode eight, that was a story that Rian wrote and was telling based on seven before we met. So he was taking the thing in another direction. So we also had to respond to Episode VIII." “While there are some threads of larger ideas and some big picture things that had been conceived decades ago and a lot of ideas that Lawrence Kasdan and I had when we were doing Episode VII, the lack of absolute inevitability, the lack of a complete structure for this thing, given the way it was being run was an enormous challenge.”
But Marvel did have a bad run similar to this one. Thor 2, GotG 1 (writer change), Ant-Man, the dispatched Inhumans movie, and Favreau's departure were all in short succession. And around that there are the numerous typical reshoots, rewrites, etc... that happen for most movies.
