What I want from the movie:
Marshadow befriends Au Ash but dimension-traveling stuff ensues and Marshadow arrives to canon world in Alola. Plot continues either in the series or in the 2018 movie.
What will probably happen:
Ash gets cucked again.
I'm more dissapointed that no else has commented on the fact that Ash looks like a dork with his OS outfit compared to everyone else. I almost want someone to roast him for that in the movie.
Don't you get it? Even when Ash does something good people will nitpick with "Yeah, he used strategy, but why didn't *insert nitpick* happen as well? Terrible episode."
