My feelings about it are more nuanced than most opinions I’ve read so far. The American Way to me is summarized in our Declaration of Independence:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
I never had and never will have an issue with using The American Way in Superman’s slogan. I’m quite proud to be a citizen of a country that strives towards those ideals. To echo @TravisMorgan, we are not perfect, but we have made great strides in our pursuit, perhaps more than most other countries.
I also don’t have any issues with “A Better Tomorrow”. I mean, who doesn’t want that? It may describe the story they’re trying to tell well, with Jon wanting to take a more “active” role in changing the world than his father. For my money though, I would have been more interested in stories that exemplify what the American Way is, based on that very excerpt from the Declaration of Independence.
Either way, not something I’m going to get worked up over. Will read the stories and see how they hold up.
