The show was/is great, but I hate when shows jump between periods in time without making it clear. Just throw the date down at the bottom of the show, especially when half the characters don't show signs of aging over that long for various reasons and technology is stagnant
All that said, the TV show is doing an amazing job of filling in Asimov's writing defincies. His character work was always shit, but I'm invested in the people from the show.
