Lately I've been doing a Deep Space 9 rewatch since the Delta Flyers guys (Garrett Wang and Robert Duncan McNeill, two of the regulars from Voyager) started in on DS9 after doing their episode by episode review of Voyager, and they brought in the actors who played Quark and Dax for it.
Man, it really holds up extremely well. Nearly through the first two seasons, which were generally regarded as fairly weak, and there are some real heavy hitters in there that, if anything, resonate even better in the post-GWOT era.
Just wish Paramount would do a real remaster like they did for TOS and TNG. I'm watching an AI upscale available on the seven seas, but apparently most of the effects shots were composited straight to video rather than on the film stock and would need to be totally remade. But lord, DS9 deserves the love.
