The film was really good, I really enjoyed it. I think it would be better if it was made before the endgame. I loved how they showed Natasha's and Yelena's bond throughout the movie. The whistle was everything, showed how close they are. Literally cried a river at the end, where Yelena visited Natasha'a grave and how she whistled but didn't get a whistle back. that killed me. i mourned Nat's death for days when i watched endgame. after watching this masterpiece, i am going to mourn again for a few months
