On a side note, due to your constant recommendations, I've begun checking out Babylon 5.
The only thing I can say BSG consistently does better than B5 are the acting, music, and effects (naturally, given BSG's decade of CGI advancement going for it). The last two are granted, especially due to Babylon 5 being on a much tighter budget (without a major network's backing). However, the only thing I'm unimpressed with so far is the acting. Really the only one who stands out is Michael O'Hare as the Commander (Sinclair I think). The guy is wooden and uninteresting, a bad thing for your expected focal point of the show (being Valen and all).
This is a common gripe. A lot of people don't like Sinclair. To be honest, every time I rewatch the first season, I like him more. Michael O'Hare does something that we never get to see. He's meant to be wooden, and distant. I know that sounds odd, but he's meant to be this somewhat off-kilter character and the point was he'd change as the series continued. Regardless, I found that out much after I began liking Sinclair. As you say, as the main character you expect him to be very different, but if you accept Sinclair for what he is, not what you expect, I think you'll like him more.
A thing to realise about the acting is it's quite theatrical. JMS 'cut his teeth as a writer' (as he says) in theatre. So he writes theatrically, and the actors overact because of the theatrical nature of the show. BSG on the other hand, is far more 'movie like' (and the tendency is for that kind of approach now) and the acting is different.
The odd thing is that the accomplished stage actor, Michael O'Hare, is the biggest exception, downplaying virtually everything, making him seem even more wooden. I gotta say, I love Sinclair, but I can see why he would aggravate people.
Also, about the CGI - as you say, there's been great advances in the effects. What it's worth noting is this - B5 was the first tv show to use full-on CGI effects. This show is the reason BSG's effects are so great. It pioneered them. I remember when Crusade, the spin-off for B5 came out - the human CGI in it is abominable because it was theoretical at the time. But I'm sure you're not too bothered by a weakening of CGI. You wanted dated effects, check out the original Trek.
I'm looking forward to Season 2 merely for Boxleitner's character to take over. Other than that, however, the show is great! I'm very intrigued by the Vorlons, and their entire culture (the little we've seen so far, mostly in The Gathering), was pretty intriguing...I like the idea of alternate atmosphere environments on the station, as well, though logic kind of dictates their necessity given the show's subject matter. So far it gets a 3/5, though once the underlying plot of the series is addressed more, I'm sure my interest will increase and my rating will as well.
I'm so glad you're liking it. Try to avoid spoilers as best you can, but it doesn't matter, a lot of it is already kinda open, even from the first episode. And what a great first episode "Midnight on the Firing Line" is.
When you get into it, you should get a B5 thread going. But I'm glad you're watching it - you're in for a great run.
