TNG is my favorite TV science fiction. I can’t narrow a list to only 5 or 6.
The Wounded (Stunning episode on PTSD and Cardassian/Federation intrigue) Sets up DS9!
Inner Light (Patrick Stewart’s best performance in this series)
The Measure Of A Man (human rights and dignity extend to AI)
Q Who (we meet the Borg!)
Best of Both Worlds (parts 1 and 2. Borg invasion)
Tapestry (another great job by Patrick Stewart)
The Klingon Episodes are among my favorites and are almost like a different series within TNG)
The Emissary (Worf reunites with Ambassador K’Ehleyr)
Sins of the Father (pivotal moment in Klingon history and for Worf)
Reunion (Worf and K’Ehleyr reunite for the final time. Another pivotal moment in Klingon and the series history)
Redemption (Klingon civil war. Setup by events in Sins of the Father and Reunion)
I find it very hard to choose between Babylon 5 and ** DS9**. They are both great thrillers based on space intrigue.)
Crossover (my favorite Mirror Universe episode within Star Trek)
The Maquis (rebel cause shows not everything in the Federation is perfect)
The Jem’Hadar (It’s the first indication that a very powerful enemy is out there.)
Improbable Cause/The Die Is Cast (2 parter, Odo and Garak’s unique series story arc begins here)
Way of the Warrior (shit gets real as DS9 is weaponized) Worf is back!
Little Green Men (Trek’s take on Roswell NM and UFO’s)
Our Man Bashir (The Doctor and Garak’s best adventure)
Trials And Tribbleations (well done crossover between TOS and DS9)
Call to Arms (the beginning of the Dominion War)
The Siege Of AR-558 (a rare and well done Infantry combat episode) A reminder that close quarters combat is brutal no matter what time period in history it’s fought.
It’s Only A Paper Moon (another fantastic PTSD episode from Nog’s perspective)
I could easily list a dozen more great episodes from the Dominion War arc.
