Joe Johnston’s Captain America: The First Avenger (B-) is an old-fashioned comic book adventure with Chris Evans as a weakling who volunteers for an experiment that turns him into a super-soldier in WWII and ultimately a superhero. Evans is appealing as the noble hero, and sequences with his buddy played by Sebastian Stan set the stage for some of the most emotional elements of this series. The plot with a villain called Red Skull comes off as a bit cheesy. Overall, it’s a colorful entry into the Marvel canon and a soaring showcase to the original agent with shield.
