Samaritan snare. It's also the one where Picard gets his heart fixed.
One where the season 2 doctor replaced Crusher (because apparently the producers didn’t like Gates McFadden even though the cast and viewers did) performed the operation.
And another where Q sent Picard back in time (kind of) to undo the incident that lead to his heart getting stabbed.
The latter episode hasn’t aged well because of one unnecessary romantic/sex scene. Which is a pity because it’s an otherwise fantastic episode.
But then the TOS has its fair share of cringeworthy moments for modern audiences that made total sense in the era it was aired.
Meh. I give huge passes for media based on when they were filmed. Stuff that doesn't age well is mostly just "well, it was ok at the time" and move on. TNG has very little in it that isn't really timeless.
Now, for stuff that was bad even for the time, that's the stuff that should rightly be condemned. For example, Code of Honor.
Not trying to be intentionally obtuse but — what is this referring to? I watched this episode recently and it seemed fine.
