Just interested if there’s an episode of a particular series you find yourself going back to? Not necessarily “the best” or your favorite, just one you gravitate toward for a comfort re-watch? Here’s the episodes from each series I find myself re-watching a lot:
TOS: Mirror, Mirror (instant classic, love the episode)
TNG: The Offspring (favorite Data episode, gives me a lump in the throat)
DS9: The Visitor (similar feeling to The Offspring)
VOY: Blink of an Eye (brilliant episode, even if it apparently rips off a novel but it’s cool to see the concept on TV)
ENT: Similitude (love the drama, love the theme and emotions)
DIS: Need to rewatch the first four seasons to find an episode that I’d want to rewatch
PIC: Vox (Okay, for the ENT-D reveal…)
SNW: Momento Mori (the first season is way better than the second season, and this episode is really cool IMO)
Haven’t seen enough of TAS, Prodigy, and Lower Decks to select any.
TOS - Honestly, probably one of the cheesy episodes like The Way to Eden
TNG - Remember Me, I like the premise and that it’s a Crusher episode
DS9 - Bar Association, still as relevant as ever plus it’s got the Ferengi in it which is always fun
VOY - Let’s not kid ourselves, it’s Threshold
LDS - I, Excretus, I really like Boimler not only passing a test designed to be impossible but refusing to accept anything less than a perfect score
Everything else I either haven’t watched, watched too recently to have a comfort episode yet, or is too story driven for one episode to stand out over the rest
