It's the same character we all love, same humor. You can view it as a stand alone mini-series, not as a continuation of the MCU movies. It's fun for what it is... just don't go in with high expectations.

The people who are disappointed probably expected lots of fights like in the movies... This one has fight scenes, but not as much or as good as the ones from the movies (they're still good though)

I'm writing this review after watching 4 episodes, I will see how the other two go.
