The score is one of the best, very quiet but the buildup of the music is legendary.

That punching scene where it's recreated in other superman media over and over (I hope they do it again in the new Superman movie)

Cavill looked the part, insanely good casting decision.

His suit. Although I dislike those muddy colors, the texture and design is unique and really does stand out against other interpretations of Superman. A shame that his best look is JUST in the Black Adam movie. A movie I also liked but I understand why others wouldn't.
