B5 was pretty slow to start, but I was definitely hooked by the last episode of season 1. It petered out for me after Season 3, since they managed to wear out the Oh My Gawd! (OMG) factor.
But I think B5 brought some interesting changes to the television sci fi scene, the chieftest being a definite lifespan for the series. I like the idea of a begginning, middle and end for the show -- and shows that have since copied it -- simpley because there were some shows (like the Next Gen) that should have been put out of my misery a lot sooner than it was.
