1. Guardians of the Galaxy - the combination of fresh settings, a big cast of new and dynamic characters, and the right balance of great humor and action came together to make one of the most enjoyable superhero films of all time
2. Captain America: The Winter Soldier - added some much needed seriousness to the MCU, raised the stakes of the universe, and stands out as an extremely compelling thriller with great performances all around
3. The Avengers: Age of Ultron - suffered a bit from "same old same old" syndrome but still very engaging and fun. Finally seeing the Maximoff twins and Ultron in a film is the main highlight, and I happened to love all three performances, especially Elizabeth Olsen who I look forward to more from.
4. Thor: The Dark World - I love the unique settings and characters of the Thor films but this, while slightly underrated, was largely forgettable thanks to a boring villain and a plot that went all over the place.
5. Iron Man 3 - Just blah and forgettable and feels too isolated from the other films. The twist, while amusing, really made me lose interest in the action.
