I guess maybe we do have a bit of a Vader oversaturation in the spinoff material nowadays, he’s easily the most fleshed-out character in the modern EU. Even then, I would still like to see a movie featuring Vader. Maybe Vader could be the main villain in a movie featuring a group of former Jedi, like someone here suggested? That could be pretty cool.
Why I reacted so strongly against Nolan directing it, though, is because I don’t like his movies at all. The plots are nonsensical, the characters are one-note and flat, and the sound mixing is awful. Maybe it’s just a case of hype backlash on my part, but I think he’s massively overrated. His new movie Tenet doesn’t seem like something I want to see anytime soon.
