I want to watch foundation and silo, but want to try reading them first. Unfortunately, I don't think I have any good sci-fi to watch at the moment other than those two.
Frankly, you'll enjoy Foundaton more if you don't read the books first. Otherwise, you'll be sitting there shaking you head wondering why they continuously mangle the core concept of the books so badly, despite characters occasionally directly stating how it works (only for the same episode otherwise showing utter disregard for said statement)
