We have it all, too, and my son has watched it several times over the years (counting from when he was watching the tapes I made).
My husband loves it as well and has seen all of it, except the last episode—because he says he doesn't think he can take it!
I was on the Science Fiction Roundtable at GEnie, an old bulletin board, back in the late '80s to early '90s, when B5's creator, J. Michael Straszynski, was also a regular poster there. (It's where I, er,
obtained the Salmon of Correction.
) I always read his posts; they were interesting and funny and off-the-wall.
Then one day he posted joyfully that he had finally sealed the deal and could tell us what he'd been up to: his SF show about a space station was really going to happen, and we should watch for it in syndication because it was going to be unlike anything that had ever been tried before—it was going to be a five-year series with a complete novelistic story arc!
And I thought,
hoo boy. Yarite. And didn't even check out the show, when it happened, for a year and a half, because this was just some guy on GEnie, right?
It was not the first time I have been both wrong and stupid, and far from the last time either, but I pull out the memory from time to time to remind myself of just how massively wrong I'm capable of being.
Edit: Here's the post, as archived in JMS-NEws—it's the very first post there, November 20, 1991. I actually hadn't gone and read it again until just now.
