I'm a long-time fan of TNG, in fact it was TNG that got me into Star Trek in the first place. I knew of Trek and really liked "Wrath of Khan" and "Voyage Home", but I couldn't describe myself as a fan until after I saw TNG. Now, I have most episodes memorized or at least know the title of the episode within seconds of turning it on.
My favorite charaters are: La Forge and Picard.
My favorite episodes include: Tin Man, The Defector, Yesterday's Enterprise, and the Inner Light.
I'm a big fan of the ships themselves and their histories in Trek.
