I think very very very very mcu films are even decent. ESPECIALLY post disney purchase. After phase 1 its basically all dogshit.
BUT this is a small exception. It manages to kiiind of feel like a real movie despite its tv show level, made in previs feeling cinematography, and gets major props for legitimately great action choreography and practical stunts. As well as a genuinely good message about doing the right thing, surveillance state, and standing up to the system
Best MCU movie? Yeah either it, Iron Man 1, or Captain America 1. As a superhero movie though its well below the likes of Superman 78, Raimi Spider-Man trilogy, Man of Steel, and basically any Batman movie sans Batman and Robin
