I think the finale of the first season is a bit of a let down. The solution to the TVA mystery and how the final confrontation is written is a little dramatically flat. Also, I think the show failed to have its retro-futurist design and vaguely Kafkaesque tone carry through in the finale. But those slight problems are the only issues I have with the show. 95% of this is absolutely wonderful.

I think the series has three real strengths. First, Hiddleson and Wilson are a wonderfully matched pair; much of the show's humor and pathos is derived from Loki and Mobius bonding. Second, the overall look and feel of the show is wonderfully realized; it's basically Mad Men meets Kafka meets the MCU in its art direction, tone. The first episode especially really nails the soft oppression of a nonsensical bureaucracy-the show is really funny on these points. These is a so much joy in Loki getting sick of himself and that propelling his character growth. Finally, the writing on the time travel/multiverse is easy to follow and avoids getting bogged down in excessive techno-babble.

This is one of the better things Marvel has done.
