I've been watching some Star Trek lately. The two part episode "The Best Of Both Worlds" is some of the best Television ever made. They really throw everything at you all at once. The Borg come back, the biggest danger the Federation has ever faced. Riker has a crisis about his role, and has some of his best moments ever.
PS. And my god, Riker's beard! He wears it like a king wears his crown.
