I spent $80 a pop on each season when they came out on DVD years ago. I still have them, the movies, and Crusade. I even ponied up for "The Lost Tales." The only thing I don't have is "Legend of the Rangers," and even then its mostly because besides being fucking terrible, it's just never in stock at my local Best Buy or Target. The completist in me would love to have it, but the other 97% of me just can't be bothered to track it down.
Anyway. I'm glad you all are reaching out together to try to make something happen. That being said, let's not try to pretend like this is some dark age where there be no Babylon 5.
Amazon has each season in stock with a price ranging between $25 to $40 a piece which is sometimes less than half what the sets cost when they were first released. There is no drought, the series isn't being secreted away by Warner Bros. It's still out there and if you can afford to pay for a Netflix streaming bill every month, it's likely you could also afford to just get the DVDs themselves.
Not trying to be a moonface assassin of joy. Just pointing out some perspective.
