I voted for River of Souls:
Pilot- Yes the acting was, ahem questionable but it does set the scene for the rest a bit, and its got Vorlon ships in it so it can't be that bad
In the Beginning- :shock: In the Beginning is frickin GREAT. And Ill Neutron Laser in half anyone who says otherwise
(the montage in the middle where Londo is talking about how hard the humans fought makes you proud of the whole species
)
Third Space - Wasnt THAT bad, ok it was a little far fetched but not really any more so than the main shadow war plot. And the Third Space ships were quite cool. (And Zack asking Lyta out is just cringingly painful, you gotta feel sorry for the guy
)
A Call to Arms - The story and supporting cast were a bit lame, BUT its got VCDs blowing things up in it (and Galen is cool) Not to mention a huge fleet battle at the end. The music hurts my ears though.... its not really that its bad, it just gets on my nerves...
River of Souls - W..... T..... F...... :shock: Even Martin Sheen couldnt save it. Most ludicrous plot I've seen in B5 (ever) and not even any of the regular cast (except Lochley and Corwin, and they dont count imho (not having a go at your avatar LBH
)
Legend of the Rangers - Is the one B5 related movie/episode I have never seen. So I can't comment. I hear it was truly awful though.
EDIT: One minor point though about the comment about Thirdspace, the Vorlons DID defeat them, thats why the gate was closed again in the first place...
