You're not alone, I loved that episode and 8. I thought it brought out a new dimension to 11 and the story.I must be the only person whole liked the whole side-story with 8.
I mean, it had tons of flaws but I thought it was the right choice pacing-wise and for the overall narrative.
The thing that bothered be the most was that
That their hideout was offshore in the middle of Lake Michigan, and in the 21st century according to that skyline in the background.
