After watching the first two (and only released) episodes, and after much anticipation for a Hawkeye movie or series, I can say that it has been great so far.
It's comedic in that Hawkeye sort of way, fun, and engaging, even when watched twice in two days. Kate Bishop seems to be a well put together character and plays well with Hawkeye. But the one-eyed dog is my favorite. Hope he comes into play somehow.
I'm very excited to see the rest of this season.
(I only rated this 4/5 because I have very high standards.)
