I remember refusing to watch Jodie Whittaker's first series when it came out because I thought they were going to return to UNIT for a season, and was disappointed when I found out 'trapped on Earth' was a one episode thing. Although I now have much more legitimate plot-based reasons to dislike the current era (despite really liking The War Fames*).
* It's one of my favourite serials, and one I tell people not to watch.
