This could be the Babylon 5 for the current generation. Well, at least in initial setup and general feel. Just caught up on all the videos and that's the impression I get - a whole ton of developed backstory and universe building before a single episode is shown, and a general story layout involving a very diverse set of characters.
This has been done right (B5) and wrong (Andromeda, IMO). I really hope it doesn't end up the latter.
