Yeah kind of. I'm fairly intrigued by the mysteriously shadowy people. I feel they may be new villains, and not just part of Aether.
In general though, I wasn't that excited for USM for a couple of reasons :
1) Back to a third version so soon, that to dual games instead of a single didn't sit well with me.
2) Personally, I didn't like Alola that much. I can appreciate that GF tried to change the gym formula, but Trials and Grand Trials were decent, but still not as good as gyms imo. But more than that, I disliked the Alola region itself. I found it too small and bland, and the whole game felt like one giant tutorial, with stupid unskippable cutscenes.
It's the toxic Wasteland filled to the brim with tribalism and political circlejerks
