I agree, episode 7 was outstanding. One sequence in particular was the best thing I've seen on television in recent memory. It's not a plot spoiler, but it's an experience spoiler. If anything about this show piques your interest, you should watch it utterly ignorant of anything. Don't watch any promos or trailers, don't watch any "Next week on Legion" clips, don't read any reviews. In fact, if you haven't watched this show yet, leave this thread right now.

To those considering taking the dive, I will say that "superhero fatigue" is no reason to avoid it. This is based on a Marvel Comics character, but it radically departs from the source material and from the genre.
Back to episode 7:
I'm glad that I can't binge-watch this series. Each episode deserves its own space. I've rewatched almost all of them before the next one, and I may try to rewatch all 7 before the finale. I don't have cable, so I have to wait a few days after the show airs and watch it on the weekend. I should be able to watch all 7 again without cramming.
As for its ties to the X-Men movies, a wink and a nod to the fans was fine, but I hope it ends there. I'd like to see the series go its own way, and even a single cameo would open a Pandora's Box, imo. Marvel Netflix series and Agents of SHIELD have made a bit of a mess by so self-consciously tiptoeing around the movie properties they're supposed to be related to.
Also, I really have to go catch up with
Fargo now.
