^Deep Space 9 has always had a different way about it compared to its counterparts. That's probably why it's my favorite Trek series. It pushes boundaries the other series won't even touch, which makes for great character development and compelling storytelling.
"In the Pale Moonlight" is worth seeing for Stephen McHattie's portrayal of Vreenak alone. Compare that to Andrea Katsulas' Admiral Tomulak* in "All Good Things..."
*He's like that Mexican Bee Guy in Simpsons. "Ay-Yi-Yi Picard!!"
He fares better in The Defector.
