I didn’t read it so much as “Russia Bad, therefore Superman bad” but as “what if you attempted to execute Communism with a good king?” Of course, the ultimate “good king” is someone like Superman—he can’t be bullied, threatened, subverted, or mislead, and he doesn’t really age so you don’t have to worry about the quality of his successors. Superman, if you accept that he’s still fundamentally a good person but you raise him with all the lofty slogans and promises of Communism, actually does have the ability to construct and enforce a mostly-fair system, although not without its flaws.

I do agree that the epilogue seemed to come out of nowhere, and didn’t really add anything.
