/gets zero credit for turning you on to the series, *sadface*

I'm really glad you're enjoying it! The episodic nature gets really intense in the next two seasons there are very *very* few filler episodes whose A or B plot does not relate to the over-arching plot. This is - very very sadly - the reason the show didn't do so well.

A random bit of trivia you may be interested in knowing. J. Michael Straczynski wrote every single episode between 2x18-5x7.
