Is there some sort of prelude to B5 that i should watch first?

DS9 starts real strong but fades in the end. (OMP) Well worth watching however. Voyager, horrible show. Liberal writting, cast never jelled and to much geared toward teenage boys. (7 of 9) What a name. Judge for yourself however. DVD box sets are usually expensive. Hate to go into them blind.

I'd have to disagree. I think DS9 needed a couple years to find a purpose for it. Heck, they don't really even get into the political and social rebuilding of Bajor very deeply until late in the first season, and only when the Dominion arc starts does the show really start to kick butt.

"Liberal writing" for Voyager? Guess I missed the episode where Janeway chastised Tuvok over the estate tax and Neelix's rant about privatization of social security.

well, Walter Koenig (Chekov) does show up in B5
and the redhead telepath started out as a stunt woman in hollywood, often on TNG, and later got face time as a recurring security officer on TNG, possibly even had lines in a few episode
