Maul Back in the Films
The inclusion of Saw Gerrera in Rogue One is pretty groundbreaking. It would be nice to see Maul in one final film. Of course the argument is he assumedly died in the film so that's that. I think this is flawed thinking from Lucasfilm/Disney in two ways;
1. They're overestimating the general audience remembers or cares. They don't. They just want to see a decent story and lightsaber battles. Maul looks cool, ie they'd appreciate seeing a cool looking character. Remember these people could give a *beep* about Star Wars canon either way and just want to be entertained for two hours.
2. They're underestimating the fans. If you're even the slightest fan of Star Wars, by this time with all media available you probably know Maul is still around. He pops up on facebook trending whenever there's something new about him. Also, there's a bazillion fans. The Clone Wars and Rebels aren't some subculture thing, they're pretty popular with kids and adults.
So basically joe casual movie goer doesn't care and there's plenty of people that know he's alive. Why not then.
