I didn't care much for the first part either.
It was too large a departure from B5's standard hinting that the supernatural may or may not exist to go straight to God exists, demons exist. And unlike the episodes there was a very obvious lack of a B and C story.
The second part was a better story (although I doubt anyone thought Sheridan would actually shoot a (somewhat) innocent teenager based on crimes he might commit in the future) and I did enjoy seeing Sheridan take up his old rivalry with reporters again. The comment about G'kar and Franklin being beyond the rim was nice too.
I also hope that this is enough to get more made. So everyone here better go buy it if they got it buy nefarious means!
I have another theory on the matter of the first part.
We know that JMS likes to draw parallels to myth (Shadow Vorlon conflict - Babylonian creation myth).
So what do we know about Lucifer?
According to myth he was an angel who fell.
We know that the Vorlons liked to pose as angles.
So maybe Lucifer was a Vorlon, who did some things the other Vorlons didn't like, which was so horrible/tabo/immoral/whatever to Vorlon standards that they exiled him and bound him forever into the core of earth.
Then the daemons could be some of his creations (likely the reason for his punishment), maybe Humans pushed in the direction of what Ironheart became in "Mindwar".
But to torment Lucifer further, the Vorlons didn't destroy his creations, but bound them into the same prison their master was in.
This could explain were "our" legend of Lucifer and hell came from. We saw it as an angel rebelling against God and being cast down by the loyal angles, were it "really" was a fight among the Vorlons, appearing as angles to the Humans.
And his turning Humans into monsters would explain why the devil (aka Lucifer) was supposed to corrupt Humans.

Actually lets take that idea a little further....
Lucifer has always been seen as an agent of chaos so what if this Vorlon's unspeakable crime was to embrace the Shadow philosophy of grown through conflict?
