Heh, that’s fair, I think everyone was asking that question, especially during the Red Hulk fight. Vibranium only goes so far as an explanation for superhuman feats, I think. Still there was more nuance in the story and moral goals of the movie than I noticed at the time, but it did end up feeling like kind of an empty bridge to the next MCU thing rather than its own story. Ah well, it still wasn’t the worst.
