Each of these shows represents hundreds of millions of dollars of quality sci fi. Rescuing it and future-proofing it for that relatively low amount of money (you could barely do 3 new episodes of a sci fi show for that) just seems like it would be a sensible decision.
I guess the question would be: does it make the shows any more valuable to CBS than they are now? These shows are only going to get older and the fanbase is getting older as well. Is there going to be a huge demand for these shows in five to ten years?
Both Netflix and Amazon write checks for $50 million plus for just 10 episodes of a new show, and so to get 170 episodes for $15 million, or whatever, would seem to me like a bargain....
Depends on whether or not those remastered shows would drive a spike in new subscribers? Are there a huge amount of people that are going to rush to subscribe to Netflix to watch twenty-year old reruns?
