I dislike giving anything a score of 9 unless it truly deserves it. I and have yet to score anything 10.

This is a fantastical Marvel series with highly intelligent dialog. You will have to keep yourself on your toes and listen to everything carefully to understand the big picture and where it's heading. I recommend watching the series on a computer with a nice display, this way you can pause, rewind and dig into texts on the screen that have very important impacts for future events. Marvels best work in my humble amateur opinion.

There are a handful of redundant lines of dialogue meant to help those, like me once or twice, refresh our memories. This may take away from the experience however, as some of Loki's questions make him seem unintelligent making him look foolish asking about such things that he is certain to know the answers to. That's about my only gripe.

The music is great, script is top-tier, acting pretty great but there are some amateurish side actors that are definitely visible and have decent couple minute long roles. Not a Citizen Kane or anything but certainly a spectacular journey sure to entertain most people if they give the mind-games and theme a little effort and reflect upon it.
