Watching the final season of Star Trek: DS9, and wow what a ride!
Deep Space Nine is the third(i think) incarnation of the Star Trek tv franchise, the last series for me to watch, and i must say it gives voyager a run for it's money as my favourite.
Dominion war is pretty bitchin' and i must say out of all the treks, i feel like the writing is the best for this one. So many good episodes, and truly excellent performances from the cast all-around, not to mention some great comic relief, particularly from some lesser-seen-yet-great alien characters like Garrak or Quark's Brother.
Another thing i love about ds9 is they have some really great "filler" episodes. Some of these standalone shows--that has nothing to do with any of the main story arcs-- had some of the best/meaningful performances of the series(sometimes from the most unlikely of characters), and are among my favourite episodes.
