Iron Man 3 (2013, Movie)

The special effects are good but the plot is dumb. There are scenes that are just nonsense, the entire Mandarin timeline goes nowhere and what Extremis actually does to its host is never really thoroughly explained. Objectively it was a fun popcorn movie and nothing more, but as a part of the whole that is the increasingly extensive Marvel Cinematic Universe, this is far from among the best the series has to offer.
