This might be controversial to say but this is my personal favorite MCU movie. Up until this point, nothing had been done like this in film and it was executed magnificently. Going into this movie in 2012 (having only seen Iron Man beforehand) I was skeptical and not interested. Then my brother took us to the theater to see it and it was one hell of a blast. I was blown away and wanted to watch all of the other Phase 1 movies and learn more about these other heroes. The casting and chemistry between them is on point, the villain is compelling and gets under your skin in the best way, and Robert Downey Jr.'s humor all around is unforgettable, and how can I not mention that glorifying theme song?? Not to mention Stan Lee's perfect cameo!
