It's just a shame that the B5 team had to practically fight for every penny to keep the series running*, whilst Star Trek managed to waste so much on Voyager and Enterprise.
I think i've said it before, but the only star trek to come close to B5 is the one that most closely mirrored it, and then only once they actually developed an ongoing story (rather than alien creature takes over secondary character/holds main character hostage/gets jiggy with junior character episode #137).
I would probably agree with all that, although I still feel star trek next gen is the best star trek.
*Wasn't it very nearly cancelled at least 3 times, including them not knowing if they were going to be able to do the planned season 5 until after season 4 had wrapped up (iirc they ended up tying up a number of plot points early, resulting in them being rushed into a couple of episodes instead of over a series).
Yep, unfortunately they rushed the 5 series and some of the 4th iirc, bit of a shame.
They also brought out a few films and an extra series (crusade) which I feel could have had a similar long life to b5 (it was starting to get good and then they stopped it

) but networks killed it as they're only after the quick buck.
I can't say b5 is better than star trek as they take a different approach, b5 is big story with mini stories inside it, while generally speaking (except ds9) star trek is more of an episode per story approach.
However I have bought the b5 box set, something I haven't done with star trek although that could be due to their extortionately high price tags, no way is a star trek series worth over 200 quid!!

The recent comeback story (the lost tales) isn't half bad even though all the old cg models had been lost, annoyingly the box set for b5 + lost tales is actually cheaper than buying the box set which I bought via the rainforest place
Now here's a detour, I consider farscape superior to star trek in many ways too and I think the andromeda ascendant is damn better looking ship than the enterprise (plus theres lexa doig and laura bertram - romy/romi and trance)

The white star rules though
Try it with star trek and b5 spelt correctly
Star trek - 43 500 000
babylon 5 - 5 660 000
