Guys, as a huge fan of the original series, I'm suggesting for everyone to reserve your hype.
*We have no idea if the animation is going to be like it was in the original series, or if it'll be 'updated.'
*All of your fond memories of the original series is based on Seasons 1-4. The 5th season was shit. The animation studio was changed to somewhere in the Phillipines, and they tried to appeal to the very young children audience (like 5 years old) and this new series is supposed to be a continuation of that.
*Bet you didn't know in the series finale that Xavier was infected with something that would have killed him, but Liara (his celestial girlfriend) came to take him away to her empire where their medical attention would be needed to keep him alive, so he'd leave the X-Men and the planet forever.
*Disney loves infecting properties they acquired with their social issues & politics.
So at the very least wait until there's a trailer that shows the animation style before getting excited.
