Foundation doesn’t want to be Foundation. It wants to be the heady, thoughtful, revelatory first season of Westworld, so it pontificates about politics and religion and souls, but it doesn’t have the depth to say anything important. The TV series also wants to be Game of Thrones with its political manoeuvring (most of which is invented wholesale for the show), but once Hari Seldon’s spaceship takes off, those imperial politics have virtually nothing to do with the Foundation. It also wants to be a sci-fi action show.
It’s so busy trying to be all of these things that it doesn’t have the time to be Foundation. For people who don’t know or care about the source material, the result is extremely pretty but not particularly compelling sci-fi. For people who know or are fans of Isaac Asimov and his work, I feel compelled to warn you that if you watch the show you will see a scene so enraging that you will tear your TV in two with your bare hands; then you’ll realise how utterly unnecessary the scene was, and tear it into four."
