Iron Man 2

Iron Man 2 has more moving parts than the first film, and while not all of them come together, it's still an entertaining sequel. Jon Favreau deserves credit for directing a film that successfully expands the Marvel Cinematic Universe while preserving the humor and personality that made Iron Man such a success. Justin Theroux's screenplay introduces several important characters and ideas, but it also tries to juggle Tony Stark's declining health, Ivan Vanko's revenge, Justin Hammer's ambitions, SHIELD's growing influence, War Machine, Black Widow, and broader MCU world-building. As a result, none of those storylines receive quite the attention it deserves.

Robert Downey Jr. remains the movie's biggest strength, making Tony Stark as charismatic and entertaining as ever. Don Cheadle slips comfortably into the role of Rhodey, Sam Rockwell nearly steals every scene as the hilariously insecure Justin Hammer, and Scarlett Johansson makes a confident debut as Natasha Romanoff. Mickey Rourke brings an interesting presence to Ivan Vanko, even if the screenplay never fully develops him.

The Monaco race sequence is one of the trilogy's best action scenes, and the finale delivers plenty of entertainment, even if it lacks the emotional impact of the original. Iron Man 2 may be overcrowded, but its cast, humor, and world-building make it an enjoyable chapter in the early MCU.
