A new season begins with much more challenges and adventures that follows a new generation under the leadership of Captain Picard, who leads the group and goes beyond the space, in order to discover new places. In this new season, the team has to return to the period of 1800, in order to get him back.
By the time Season 6's "Relics" came around the show's trips back to the Kirk/Spock well had perhaps gone too far...But it's Scotty's session with Picard that provides one of the finest moments in all of Trek.
As a whole, Star Trek: The Next Generation Season 6 might well be the finest complete season the series ever produced and well worth a look or a re-look.
The Next Generation take is darker and more politically progressive: Torture is counterproductive for the interrogator and devastating-both physically and emotionally-for the subject.
