The concept of the TVA is pure gold. You're right, it's a bureaucratic nightmare from the 1970s overseeing all time and space. That mix of cosmic power with filing cabinets and piles of paperwork is what makes it so unique and interesting. And the twist that they're all variants with their memories erased is brutal. Suddenly, the “good guys” who maintain order are victims of the same tyranny they are enforcing.
Sylvie is the best part! At first, yes, you think, “OK, another Loki,” but she's the antithesis of our Loki. While he always had a life of privilege (even if he felt excluded), hers was stolen from her. Her thirst for revenge is totally justified, and that's what makes the romance so complicated and fascinating. She was ambitious, risky, and left us wanting more.
