I was long-time fan of TNG when DS9 came out. Now, DS9 is probably my second favorite series, though at times it edges out TNG during the Dominion War. The large scale space battles and Sisko's internal conflicts are what made me a fan. I think it was the moment that Sisko directly referenced Wolf 359 to Picard, I knew I was going to be a fan.
My favorite charaters are: Sisko and Worf.
My favorite episodes include: Way of the Warrior, Call to Arms, and In the Pale Moonlight.
