It will be interesting to see your reactions as the series unfolds. The first season does take a bit of time to get going but mostly due to setting up character backgrounds and so on. As you work your way through it all, you can go back and see where subtle details are used to construct that atmosphere.
A good resource site is The Lurker's Guide to Babylon 5
. It's organized primarily by episode, so you can look into details as you watch each one, without fear of being spoiled - if that happens to be a concern of yours. Above all... post your honest opinion about what works and what doesn't, what's well-done, what sucks and what could stand a little more polish, etc
One addendum on the actors' deaths ...
- - Richard Biggs (Stephen Franklin, the doctor for most of the series) was the youngest at age 44.
- - Tim Choate (a favorite recurring character "Zathras")
- - Andreas Katsulas (G'Kar and you may have seen him in TNG a few times), Jeff Conaway (Zach Allen also was in Taxi, Grease), and
- - Michael O'Hare were all in their 60's
