Iron Man 3 (2013)
A fitting end to the trilogy
Iron Man 3 is definitely the funniest out of all the Marvel films. We get to see a lot more of Tony Stark as a person - his intellectual prowess, and charismatic sense of humor rather than Tony Stark as Iron Man. The rest of the cast is also great. Gwyneth Paltrow is still an awesome Pepper Potts. All around enjoyable film.
Enjoyable superhero movie
Aside from some plot holes and a too long runtime, the intense set pieces, clever twists, sharp script, and great performances make Iron Man 3 a blast. Superhero movies don't get much better.
