I love character pieces that really explore who these people are beyond the science and technology of the 24th century. So that said, my Picard faves (in no particular order):
1. Tapestry
2. Lessons
3. All Good Things
4. Family
I wish people would stop saying Tapestry is a great Picard episode. It's mostly about his personality as a youth. It's an interesting and important episode, but it doesn't show who Picard is now.
Having read your posts I do realize that you love to use inflammatory language. That said, why can't "best Picard episode" include plots focused on his earlier years? Wasn't he still Jean Luc Picard? By looking to the past you can really understand why he is who is he now, which makes is relevant.
It is relevant. I specifically said "it's an interesting and important episode." But it does not highlight what's truly remarkable about Picard as do more standard "Picard episodes" like, say, Darmok or Inner Light or any of the others. I hardly think that is inflammatory. All it is showing about his character is that he was a brash youth whose personality had changed significantly, and the importance of his early encounter with his own mortality to his later personality. But it does not show the depths of that later personality.
The reason it is not a
great episode, is that it has so many Q scenes. Q is just miscast, he's too obvious and ham-handed in his obnoxiousness. Obviously Q is not as bad as Wesley, but you cannot call an episode "great" when one of its main characters is portrayed (from the standpoint of writing and of acting) with such lack of subtlety.
I do not think any of these three claims are "inflammatory":
(1) Although important, Tapestry does not show what's remarkable about Picard's personality in the way that other episodes do;
(2) If a major character in an episode is badly acted and badly written, then that episode cannot be "great"; and
(3) Q was badly acted and badly written.
In truly "great" episodes, like say Inner Light, the performances of the supporting actors are also strong, but certainly not horrible, and
certainly not hammy and over-acted.
