Having taken the time to watch the entire thing again in glorious HD, and with every episode refreshed in my mind, I think it's time to pick out the ten best episodes in the series.
a Man (Season 2, Episode 9)
Since the original series featuring Captain Kirk, Star Trek has always dealt with some pretty philosophical subjects for a TV show. It's easy to forget that sci-fi on TV or in movies was really superficial and shlocky up to that point.
What really got me about this episode, however, is how it shows that the values of the Federation don't always live up to the practice of it. You'd think that the ultra-progressive Federation would never even doubt Data's right to life and autonomy, but human nature being what it is, there are still people who'll tie themselves in philosophical knots if the ends justify the means.
9Darmok (Season 5, Episode 2)
One of the most famous episodes ever, and one of the few that broke containment outside the Trek fandom, Darmok tackles the question of how aliens with a very different conception of reality can communicate with each other. The Tamarians speak words that the universal translator can turn into English, but the actual meaning of their phrases is not apparent. What does "Shaka, when the walls fell." actually mean?
Picard eventually figures out the gimmick of the Tamarian language, but not without a major sacrifice. There are, of course, lots of plot holes in this one, so it's best not to think too hard about how this would all actually work. However, the actual questions posed by the episode, and the stellar performances, raise it to the top of the TNG episode ranking. It's like Arrival, but on a TV budget.
8The Offspring (Season 3, Episode 16)
The Offspring is a memorable episode for me for a few reasons. Not least of which is that I missed the second half of this episode, the first time it aired in my country, and had to wait years before I got to see it again. Remember missing TV show episodes?
Anyway, in this episode, Data expressed the desire to procreate, and it doesn't involve showing Tasha Yar how "fully functional" he is. Thanks to advances in the Federation's cybernetics technology, Data thinks it's finally possible to build himself a child. Named "Lal", this new android is at first a blank template, and Data leaves it up to them to choose not only their gender, but also species.
However, we aren't treated to another lengthy court case, but instead a bittersweet daemon ex machina resolves the issue.
7The Inner Light (Season 5, Episode 25)
Picard is zapped by an energy beam from an alien space probe and wakes up as an alien man from a planet called Kataan. Seeing no other way out, Picard lives as Kamin, the iron weaver. He marries, has children, and learns to play the flute.
Kamin notices that an environmental disaster is coming, and eventually the government admits it knew all along, but can't do anything about it. The planet's life will go extinct. The people of Kataan decide to create a probe and transfer the memories of their people to it, so someone out there will know they existed. Picard awakens after living for decades in the simulated world, but only 25 minutes have passed in the real world. It's pretty harrowing to think about, but at least the Captain now knows how to play the flute. A flute that makes a cameo in many episodes later.
6Who Watches the Watchers (Season 3, Episode 4)
The "Prime Directive" of Starfleet is a strict policy of non-interference by Starfleet with cultures that haven't yet developed warp technology on their own. This has been a great source of conflict for episodes, and while the Prime Directive forbids direct interference, it apparently doesn't prohibit spying on these more primitive cultures for scientific reasons, because apparently privacy is only a right afforded to those with space ships.
So, Picard and his crew have to try and undo the damage they've done, and part of that solution is simply treating the Mintakans like grownups, but the episode brings up some uncomfortable questions about our own history of dealing with people in civilizations who weren't as technologically advanced.
5Datalore (Season 1, Episode 12)
Datalore is one of the few truly great episodes from the much-troubled first season. It's a crucial part of Data's backstory, where we learn more about where the enigmatic android comes from, and why Starfleet isn't swarming with Datas.
4Chain of Command (Season 6, Episodes 10 & 11)
This two-parter does a lot of heavy lifting in the TNG canon. Not only do we meet one of the most reviled characters in Star Trek—Captain Jellico—played to perfection by Ronnie Cox of Robocop fame, it's also the origin of the famous "There are FOUR lights!" meme.
Captain Picard is captured and tortured by Cardassians while on a covert mission, during which Jellico is given temporary command of the Enterprise. Jellico won't admit that Picard was on an official Starfleet mission, and so he gets no rights as a prisoner of war and therefore has to undergo relentless torture.
This one is pretty heavy, and deals with subject matter that's perfectly at home in any realistic and gritty war movie, but it's also one of Patrick Stewart's absolutely best performances in the role.
3Q Who (Season 2, Episode 16)
The godlike being Q, who features in the very first episode of TNG as humanity's judge, returns with a demand to join the Enterprise's crew, ostensibly because he fears that Picard doesn't appreciate the dangers of the new regions of space they are exploring.
Q yoinks them back to safety, but now the Borg know about the Federation, and they are coming. This episode scared the heck out of me as a kid in the 90s, and it's still effective at portraying one of sci-fi's greatest villains today, until later Trek portrayals of the Borg sort of ruined them.
2I, Borg (Season 5, Episode 23)
This brings up the dilemma of trying to save civilization from the Borg or committing genocide against the Borg. In a lesser sci-fi show this wouldn't even be an issue, but this is Star Trek, by Riker's beard, and here we try to do the moral thing.
1 Day (Season 4, Episode 11)
I prefer Data's Day to Lower Decks (Season 7, Episode 15) as the best episode that shows us a little more of what the more mundane part of ship's life is like on the Enterprise, and it's yet another episode that further develop's Data's character. There's a subplot involving a Romulan sleeper agent, but really this is all about how Data spends his day on the ship living among the crew.
This episode revolves around the wedding of Transporter Chief Miles O'Brian and Keiko Ishikawa. Data is asked to give the bride away, so he spends his time learning what he needs to do during the wedding in this role. Oh yes, and he solves that whole Romulan agent murder mystery thing in between tap and ballroom lessons.Picking just ten episodes from the whole TNG series is hard. Well, apart from the first season, which is mostly bad episodes with a few gems. Honestly, it's a miracle a second season was made, but man am I glad they persevered.
