Oh, really now... one has a better premise yet the other has a better execution... So when I whine "oh, really now" I mean it's a tough call between two where either has every right to win because both are the less of the sum of their parts.
"We'll Always Have Paris"
TNG's version of "The Alternative Factor", it's an interesting high concept sci-fi outing involving temporal mechanics, with great effects (since those alone make a story more than the scripting and characterizations, right? Right? Well...) and yet it's mostly forgettable and even the late-80s haute fashion dress was low rent compared to the lesser fare of "Dynasty". :
(honestly, just rewatch this and pinch yourself every time you think he's Lore three times over... also, isn't that lightning stream in the middle the same effect used when the Vger Probe digitized Ilia after roaming the bridge in TMP?)
Ragging aside, I did like the introduction of fencing, the music, and the chronic hysteresis as I recall the makers were fond of
Doctor Who as one of the best examples of that was displayed in "The Neutral Zone", where sadly the blu-ray restoration did not allow a bonus feature clip of the original text in EZ-To-Read HD, but the fact people could discern the original names of all the Doctor Who actors in fuzzy SD in 1988 is sufficiently charming anyhow...
(2:49 in you'll see the actor names. Just go to that mark because a boring scene with the TMP Enterprise model littering the background is bit of a chore for this digression-within-the-digression, and also while noting the video's tag line that now leads us to this gem:
(yup, it's six degrees of
something as nothing is truly in a vacuum, unless it's a defective vacuum but those suck...))
Plus, every time I hear "Manheim" I think "Manheim Steamroller". Mosey down to YouTube for a bit of that and even music snippets of that are just as awkward in the context of this episode too, which is saying a lot given how awesome this episode's score is!
Lastly: A story with far more potential with the prime directive and trying to have the guts to off a main crewmember with some depth*, the complexity and philosophical depth attempted for
Justice should have led to a home-run had it had the time for enough rewrites and less oversimplification, and the less said about Wesley's one-liners (save for one) the better. What we got was a foul ball, hit by a team of baseball players that ate too many beans.
* I'm not discounting "Skin of Evil", Yar's death was shocking, part of a setup that had audiences worried for the other characters as well, and it'd have been corny if they spent 35 minutes building up to her being killed at that point...
Now when I say one-liner, it's not the "I'm with Starfleet" gag (literal gag, not comedic) but where he rightly brings up that he should (have a say) since he's the crux at all this, in a brief and curt scene.
MUCH DESERVED WINNER BECAUSE IT'S THE LARGEST STEAMING PILE ON THE WALL
