Re: I liked DS9 and the Dominion War, would I like Babylon 5?
I don't like comparing the two myself, especially not in the sense of which is a "better" show. It's apples and oranges to me; B5 is a great example of how a tv show can work very well when it's pre-conceived and plotted out from the beginning. DS9 didn't have that advantage, and sometimes it shows...but then, doesn't that make it more impressive when it holds together well despite not having been pre-planned?
Anyway, I think B5 is definitely worth a watch, though much of S1 can be skipped IMO; much of the (often minor) arc-building that occurs in that season may be more fun in retrospect than during a first run. S5 is also less than stellar during the first half, though it picks up with a vengeance later in the season.
Then there's the spin-offs...
It was the best of Trek, it was the worst of Trek...
