I've been listening to a B5 review podcast called The Audio Guide to Babylon 5, which has spurred me to thinking about the series again and contemplating doing a rewatch that uses an episode order that is an amalgam of the episode order as outlined in/on the Lurker's Guide to Babylon 5 and my own personal observations as follows:

The Deconstruction of Falling Stars
Notes:
* The War Prayer is moved to between Soul Hunter and Born to the Purple in order to make its narrative 'flow' better and to use Londo's actions in deciding to help Vir's nephew and his betrothed marry for love as 'setup' for his own 'love relationship' with Adira in Born to the Purple
* TKO is moved to between Infection and The Parliament of Dreams in order to make its narrative 'flow' better and to create less of a tremendous gap between Susan's father's death and the point in this episode where she lets herself mourn for him
* Believers is omitted because it's just not a good episode by any stretch of the imagination and I personally cannot stand it
* The Deconstruction of Falling Stars is moved from Season 4 to Season 5 because I believe that it serves as a much better series finale than Sleeping in Light, which is omitted
