Controversial opinion you have there. Depending on how Mandalorian crosses the finish line, I might agree.
Mandalorian immediatly proves this wrong. The real reason is that they refuse to adjust the budget to the movies. If they cant pump a few hundred million into it, and get a billion out. They see it as too much work. Say what you will about marvel, but theyve had spy movies, fish out of water, heist movies, wierdo space adventures. People fucking love it, you just need to do it well enough. Like look at how exceptional endgame is on a surface level, yet people still loved it.
