An excellent read and like the other reviewer, I'm surprised it's never been made into a movie.
In addition to character elements which could have inspired the creation of Superman, I find many elements here (eg,the serum that created Hugo's strength) that could have inspired Captain America as well as Spider-Man, given the emotional troubles Hugo endures throughout his life.
