Some of its moments are so bad that they are hard to bear. There's some uninteresting acting too, e.g. the frail Captain America and the love interest. None of the other performances are really good, and the villain is embarassingly bad, as if from some low-budget sci-fi movie. The script is bad and it's strange that the movie comes from the same studio as Iron Man. There isn't even decent visual effects to lessen the pain. Luckily, the final-form Captain America hero is fun to watch.
