Star Trek: TNG: All Good Things... (1994)

TNG's final TV outing connects directly to events in the show's pilot episode (Encounter at Farpoint), making everything that happened in the intervening seven years relevant to both stories. In order to fully appreciate the work, you absolutely must watch that pilot episode before watching AGT....
Central to the story is Capt Picard, whose consciousness is hopping between a number of fixed time periods like some kind of 24th century Billy Pilgrim. He's in almost every scene, but Patrick Stewart is up to the task, whether it be as a man full of confidence, of doubts, or seemingly bordering on senility.
A further benefit in connecting itself to the pilot is its ability to comment on TNG as a whole, in a way that's both reflective and contemplative.
It's sad to see a beloved show end production, but TNG's ending is perfect, drawing a knowing line under what's gone before whilst simultaneously looking ahead to the future. That duality is why I love re-watching AGT....
