If you want to watch this whole movie while yelling at the screen that Superman needs to DO SOMETHING, take action, and needs to stop being a passive deadbeat, this is the superhero movie for you.

I am, and was, familiar with the source material. I am, and was, familiar with the limited acting range of Keanu (whoah). So why do I love this movie as much as I do?
No clue. Go watch it. It's fun.
This is the movie that got me into time travel. And let me tell you, I really, really like time travel.
