My overall rating of "It's Always Sunny in Philadelphia"'s Season 8: 4/10
Overall it's been a pretty "meh" season, and this episode, while certainly the best of the season, is not a superb one. Some of the scenes don't quite land (like the bizarre conversation about the Academy Awards and Batman in the middle), but both the dramatic/horror and the comedic elements get their turn to shine and the story feels well put together and plays off the prior continuity really well. The framing really shakes up the series' routine and does so in an utterly enjoyable way.
