The torturous double-feature of "Move On" and "But I'm Not" may as well have been in Swahili or Dome-anese because I haven't the foggiest about what actually happened in it. Are we even sure they showed the right episode?
This is all derivative, of course, cribbing from The Matrix and (as always) Lost, but this show is always more fun when it leans into its sci-fi elements.
Under the Dome is certainly broadcast television's most enjoyable science-fiction/fantasy series, a summer treat that, while sometimes silly and over-the-top, is never less than energetically imaginative and aware of the history of its genre.
