Superman
I had a whole review typed out with several paragraphs discussing how much this film meant to me, how it brought me to tears several times, and how it's quite literally one of the best comic book films (if not THE best comic book film) in about a decade.
However...maybe it's best that all of that stays personal, and I just leave you all with this: I believed a man could fly. Absolutely floored by just how much I ended up loving this. Unreal.
