Thanks for making this thread!
How cool was that, to see Darth freaking Maul again in a movie?
"OK, hold on, you contradicting SoB!", you're probably thinking... Yeah, I hate nearly everything from the prequels, save Ewan McGregor and Darth Maul, who only sucked because they gave him no real purpose to the story at all, in movie form.
Just because I don't like the prequels doesn't mean I don't want to see certain things from the prequels to be validated. He is definitely one of them, and now they have given him purpose as a character. He will very likely be in both of the next spinoff movies. His existence is being written into validation, IMO. Yes, I know that he's been in Clone Wars and Rebels, but him being in this movie was clearly a setup for the next two, and he got very short-changed in Episode I.
That is all.
