It’s similar only in that it’s about a “Great man” remaking a society in collapse.

Really none of the themes are there. Nor is there any journey of discovery to understand who Caesar is, like you get in Atlas Shurgged where other characters learn who John Galt is.

Galt is “Self interest and belief in my vision will make society better”. Caesar is “McGuffin building materials and belief in my vision will make society better”. For all its flaws, one is at least a political statement, while the other is milquetoast hopium.
