Hawkeye by itself might not be at first glance a character to base a show on before so many other choices. However given a large library of comicbook stories, he definitely could be given depth and a good story woven with interesting characters.
This is not really centered around Hawkeye. It is split between too often overreacting Kate, who it sometimes seems finds people suspicious at a drop of a hat, and always tired and worn Clint. Both are very much stereotypical characters here, a semi-grumpy combat worn hero and a tag-along newbie, who marvels at him and annoys him with "witty" quips as they being finding mutual appreciation and respect. Yeah, nothing very original here in any aspect.
Neither is the story. Jack is charismatic and entertaining character played by a good actor however I think we've all seen our share of duplicitous partners and kids who notice things first.
All in all its pretty predictable and all wrapped in a politically correct and woke Disney packaging. It is not bad but neither is it great or original. It is average but I suppose also entertaining for a watch on your couch in these winter months, cuddled under a warm blanket with something to eat or drink, as it gently snows outside.
