I don't have many spoiler thoughts yet, but for me, only Loki comes even close to the level that Moon Knight. was at in this episode as far as debuts for MCU shows. Oscar Isaac kills it
If I had to describe this show (okay, episode) to someone who knew nothing, it's like Night at the Museum meets Fight Club with a tinge of The Mummy (1999). I really hope it can maintain the quality this episode was at and the tone this episode had.
Also, in the UK, this is a 16+ rated show (closest equivalent to TV-MA) that they have. It's the first MCU show to get that 16+ in the UK, however, it is still TV-14 in the US, but based on the 16+, it seems like they are going to push the boundaries as much as possible.
