A soap opera is neverending; B5 is more like a novel, with a beginning, middle and end. Watching it out of order is like starting halfawy through a book. Looking at the
episode guide, I'm not sure what I would have thought coming into season four cold.
Unfortunately, the first season is pretty choppy, so there's a whole cottage industry of recommending which season one episodes to skip... But I like them all.
Not all aspects of all episodes, but even the worst of the A-stories in an episode is usually accompanied by a decent B-story.
And the Londo/G'Kar story is one of the most powerful I've seen on television.
