12Iron Man 2 (2010)
For every good decision that the execs down at Marvel make, it's important to remember that they’re human too. They’re susceptible to errors in judgement like the best of us, and nowhere is this flaw more notable than in Iron Man 2 (2010). Coming off the surprise success of the
first film, director Jon Favreau hams up a CGI buffet of shiny fights while letting his plot overcomplicate and underwhelm. Matters are made worse by the waste of Sam Rockwell’s villain and a post-comeback Mickey Rourke buried under a debilitating accent and absolutely zero characterization.
As the third film in the rapidly expanding MCU, Iron Man 2 was saddled with the responsibility of setting up the superhero storylines that succeeded it. There’s a decent amount of leniency to be had as a result, but even with Downey’s undeniable charm, Iron Man 2 takes the bottom rung on the Stark Industries ladder. Sorry, Tony.
Update: Unfortunately for DC fans, this film may be the most apt comparison for the recently released Batman v Superman.
