A reasonable outing.
B5 - and JMS writing in particular - works better when not contained to standalone episodes. Give him space to breathe, and his musing flows far better. He has room to comment, moralise and philosophise beautifully. Give him a single story and he tries to cram in too many explanations and plot movements which start to clog up the script. This is a pity as the script is what he is good at.
So a nice story, but a little uneven. Sometimes continually underlines the same plot points over and over killing room for nice stand alone dialogue or character exposition. Other times, the character scenes (the lift scene ) are too long an neither help the story or offer any depth for their duration.
That said, the SFX is very nice, the music from Franke is far more classically orientated than before and it's a nice chance to try and highlight some of the minor characters. The story idea is reasonable, if a little unusual in scifi tone for B5 (befitting Trek more) and it lacks some of the regular B5 heavyweight actors (G'Kar and Londo are sadly missing and Delenn has few scenes).
Nevertheless, an enjoyable if a little vacuous compared to what one comes to expect from B5. The aural and visual experiences are good, the actors are solid and the story good enough to standalone. Not perfect, but still a good slice of pulp scifi action.
