It is really an amazing series. The thing I love the most about it is how it shows that anyone can be a superhero. And it also gives light to Hawkeye which in my opinion was/is the most underrated original 6 Avenger. Also, it introduces 2 or even 3 new personalities who can be the new avenger.
It also gives tribute to Natasha's character and shows the depth of her relationship with Yelena and Clint in such a subtle and beautiful way.
As many people see Nat as less emotional less attached, this proves the opposite and beautifies her character more.
Overall this is amazing series or even the best till yet marvel series.
(P.S. I have tried not to spoil it for anyone and so if you feel I cancelled major things in rating it's for the same)
