AVClub: In addition to being an all-around magnificent hour of television, “Lens” has the best kind of ending: the soft cliffhanger. Television is an ultra-competitive medium, and storytellers can’t take for granted that the same people watching any given episode will tune into the next one. The solution for this is big, earth-shattering, paradigm-shifting final scenes that leave the audience on tenterhooks, anxious to see what happens the following week. As the man responsible for writing “Guys, where are we” and “Kate, we have to go back,” Damon Lindelof knows from a shocking cliffhanger. The problem with those, as anyone who watched Lost can attest, is that if every episode builds to a frenzied peak only for the intensity to drop off the following week, the audience becomes inured to the provocation.
