B5 was a series that ran in syndication and on the PTEN tv network (it was around for a few years in the early 90's). Eventually it finished it's run on TNT. It's a self-contained, 5-year story arc. Stuff that happens in the first season will pay off in other seasons, including the last one. It's a running narrative, and is very different from say, Star Trek in that the "reset" button is not used at the end of an episode to make everything ok again. The creator/writer/producer was never afraid to drop characters down an elevator shaft, figuratively speaking, when he wanted to. Characters move on, change, and die.

Here's a pretty good overview:
