Second to last episodes usually are the best episodes in HBO shows. GoT was no different. So last week's episode was good, this one is just setting up next season...which we won't get until 2026.
I had a hard enough time keeping track of who people are after a 2 year layoff between seasons 1 and 2. That definitely doesn't help my enjoyment of the show. And I'm a guy who's watched the first show twice and read the books twice.
I think we get to a point with franchises where we reach our own saturation points and we stop being as invested as we used to be. It definitely happened to me with Star Wars and Marvel movies.
