Reason 3: The Avengers
The first phase of the MCU concluded with the first Avengers film. It didn’t disappoint. All it did was set the bar higher for the rest of these movies. They set the standard early, and everything only got better afterwards. Seeing the originals together and not have the movie watered down showcased how great the filmmakers are for these movies. Could you imagine if this movie was a flop? Would we even be talking about Infinity War. Just think about that for a second.
