Babylon 5, and watching a show years after it aired

JoDee and I are making our way through Babylon 5 for the first time. Well, I'm watching it, but JoDee is falling asleep through most of it. But what is really hard to manage is not getting spoilers for the show. Look up an actor on the net, and their entire character story and back story are laid out as plain as day. Makes me wonder about newer shows like House of Cards on Netflix where the entire show is released at once. Makes it difficult when someone has an advantage of seeing it before you had a chance.

Not complaining about "hey, spoilers" for a show that has been out for over ten years; just finding I can't do my normal show research beforehand.
