If I already watched Cosmos 2014 but haven't seen the original...
I want to watch the original Cosmos. Since these kind of reboots aren't the same kind of fiction reboots, maybe there is no difference in the content, or maybe the 2014's version is update but that one is the one I saw.
If I already watched Cosmos 2014 with Degrasse Tyson, would it be redundant to watch Cosmos 1980 with Sagan?
The advice will be appreciated.
