It's a truly magnificent film that presents the tragic story of a man who takes a flawed approach towards peace, set on a path through experiences that—despite being a godlike alien—are relatable. We see Superman in a different light, but at the heart he remains as he always was: a symbol of hope.
On a more casual note, it's been a while since I've cried in a film. The pain and the heartache really hit me in a way I wasn't expecting. Truly an excellent film well worth the watch.
