Captain America: The Winter Soldier -- The Tragedy of [AAAGH SPOILERS]. No seriously, SPOILERS. Scary, unstoppable ones that will come after you in broad daylight and take your steering wheel.
This is the point where I flush all my emotions down the toilet and go to live in an igloo made of frozen tears, because what the hell.
The entire review is great, but this section in particular has a lot to do with why I love the movie so much. Okay well, everything in the movie is why I love it so much but that bit is a) based on a truly bitchin Cap run in the comics and b) really %*$#ing emotional for a damn comic book movie. (Or any movie at all, really.) There's a scene that's especially confusing because it presents sad and tragic alongside smoking hot and MAKES ME FEEL BAD FOR LOOKING. WHY, MARVEL?
The previous sections (linked at the top of the page) are definitely also worth a read.
