The initial portion of Black Widow proved quite impactful and moving. Florence Pugh gave an outstanding performance; she was truly remarkable, particularly during the action scenes, and I appreciated the playful aspects of her portrayal. The dynamic between Yelena and Natasha felt exceptionally well-developed. David Harbour’s acting was also commendable. While the action set pieces were enjoyable, the CGI quality in the third act seemed lacking. Furthermore, I wasn't entirely pleased with some alterations made to Natasha's characterization. She doesn't possess superhuman abilities like other Avengers; her intelligence and mental fortitude are what make her so formidable, but those strengths felt exaggerated here. The film effectively depicted Natasha’s internal struggles. Although I found the movie worthwhile, my enjoyment was largely due to Florence Pugh’s presence.
