Best Sci-Fi & Fantasy Series 2023

In 2021, Apple TV+ debuted Foundation — a sprawling, complex sci-fi series based on the eponymous novel series by Isaac Asimov — as an appeal to those in search of smarter science fiction, and while critics generally thought it impressive, they also found it a little unwieldy. Thankfully, season 2 marked a dramatic improvement, so much so that it took home the Golden Tomato for Best Sci-Fi & Fantasy Series of the year.
