The past two episodes have spent a lot of time exploring Londo's rise to the top of the command chain of the Centauri Republic. Too much time, if you ask me.
I find Londo Mollari to be the most annoying character in the entire series, and to have the better part of two episodes focusing on that buffoon grated on my nerves.
Not enough time was spent during these two episodes developing the overarching series plot involving Babylon 5's role in provoking open warfare between the Shadows and the Vorlons. That comes in later episodes, but those episodes' fabric would be richer had more time been spent here and less time spent on those Centauri goofballs.
If you like the Londo character and his plot lines, then you'll love this episode. If, like me, you regret that B5 didn't kill him off in season 1, you'll go "meh..."
