Sean Gilman’s review published on Letterboxd:
Superman (in costume and flying and being superheroic) doesn't appear until almost exactly halfway through this movie.
Glenn Ford's "oh no" is a line reading that has stuck with me since I was a kid.
Also, even as a kid I knew that spinning the Earth the other way around doesn't actually make time go backwards. That's not how time works. Someone should make a video essay about this.
