I can die having seen Key & Peele AND Keanu Reeves in the same Disney movie playing characters only they could play.
Put yourself back into 2012. Marvel Studios had laid out 5 movies with 4 different heroes. Then they put out this, taking superheroes with different origin stories of their own and bringing them together for what was, at the time, the biggest movie event ever. This was never done before. EVER. And the fact that it was pulled off so effectively is just absolute insanity. Despite any other misfires Marvel Studios has or will have in the future, this movie will live on as ambitious, entertaining, and unprecedented, and my absolute favorite movie in the MCU.
