As a general show, there are a lot of cool ideas, nice visuals and great soundtrack. If this is the first story with time travel/cosmic insanity you watch than it will be a decent enjoyable experience but nothing special.

As a Marvel fan, Loki himself is such a soap opera goody two shoes by the end that no one would believe me until they see the show for themselves. At points he delivered such cheesy lines that you were so sure this must be an act. No, he was just that cheesy in reality.

The TVA was introduced as pretty powerful in the first half with all sorts of powers but they never use them later on when they'll be useful.

The final episode, while very good for the broader MCU, didn't pay off Loki's character journey at all. So much so, that I think the Infinity War end of his journey is enough. And no, just because there is a second season, it is not an excuse for such a narratively disappointing first one. In time, I only expect to remember this as that one show with the villain reveal and that's it.
