From a story viewing point of view, I wouldn't break off.
One of the things that people seem to miss is there is a lot of "layering" in the stories of the B5 universe.
The best example to illustrate this is, I wouldn't advocate people breaking off part way through Moments of Transition to watch Thridspace. Rather that when watching Moments of Transition that they bear in mind that Thirdspace takes place during that story. And when they are watching Thirdspace that they bear in mind that the events of Moments of Transition take place around this story.
I hope that makes it clearer
