The Empire’s side is just amazing. The fact that Foundation is basically not a priority for Cleon is great. I would watch a show just about the Empire. The 3 Cleon fight for power, and Trantor diplomatic relationship with other planets.
Foundation stuff is meh. Gaal is horrible. A mathematical genius who is also a ball of emotion is just bad characterization, plus it is pretty misogynistic compared to how they depict Harry.
And they better solve the mysteries they set up, or I’ll be really angry with the show. To name a few: How was Harry resurrected, by whom, and why? Why does Cleon 1st have a larger memory bank?
