I gave up on Babylon-5
early on, but was persuaded to give it a second chance by friends whose judgment I trusted, and, yeah, like TNG, it gets much better by the time you get to the third season or so. It peters out a bit near the end, though. As I recall, I kind of drifted away during the fifth season . . . although I remember catching the series finale.
Truth to tell, I was much more into XENA and FARSCAPE back then.
