For shows, Battlestar Galactica is always great. I just started watching Caprica and loving it so far. It might not be an “opera”, but it does so much to fill out the Battlestar Galactica universe.
I also just started reading The Expanse series and would definitely recommend it, even for someone like me who’s not an avid reader.
Yeah this seems false. SD cards are unreliable, hard to keep track of, and don’t actually store that much data for the price. I do think they use tapes though to store long term, low traffic data.
