Attention to detail department: I like that Madame Hydra has much more glamorous, "movie-star" hair than Aida does in the real world. Which was noticeable when they back to the real world there at the end.
And somehow, pulling her hair forward like that to frame her face makes her features look a lot more rectangular, and kind of Jack Kirby-esque, only more beautiful than any woman Kirby ever managed to draw. In Madame Hydra mode, she reminds me of someone from some older thing I saw -- maybe Jane Badler in V?
He finally got to be the hero that he always wanted to be, but he had to die for it. His death turned things around, though-- I think it was seeing him sacrifice himself to save a bunch of kids that got through to May. I hated to see him go, though, because he had developed into a really great, and likeable, character.
