I, for one, am looking forward to seeing what the Babylon 5 universe can look like. On the big screen. With today's technology. I do think original B5 effects with space battles were so amazing, but the notion of seeing a Narn destroyer slowly inching its way across the screen in a giant theater makes me truly giddy.
I've seen the original series. I fell in love with the characters and the story arcs. But they are done. I'm okay with something new coming along. I will sit in the theater and revel both in the joy of the new changes and the thrill of being "in on the secrets" that stay.
And I could see using some of the former actors. The way they used Zarek, for example in BSG reimagined? Great stuff.
My only reluctance comes from the logistical side of things. Will this really ever happen? I want to believe, but until things are more firmly in place, I'm going to err on the side of caution. (I also felt this way about GRRM's GoT, which had a positive outcome.)
Like I said above, I'll go see it whatever happens. That said, I instantly started protecting myself becuse I don't think it's going to happen, and I'm tired of getting my heart broken.
A German friend of mine who was absolutely vastly passionately more obsessive about B5 than I once said this: "Babylon 5 is like a package vacation that a Travel Agentconvinces you to go on, despite having never heard of it, and no real interest in it. It turns out to be the greatest thing imaginable, and you're blown away. The next vacation, you go to the same agent and say "Book me another one!" So she sends you someplace, and it's ok, but not as good, and you have to leave early because of a Cyclone. You go to the travel agent again and again because of how great the first trip was, but each subsequent vacation is just that much less than the one before, and finally she just ends up showing you brochures for hotels that haven't even been built yet. So you give up and go to Canada instead."
