With the upcoming release of Superman: Legacy , more people are coming forward to reveal their strong dislike of the Zach Snyder version of Superman. The main reason for this hate is because they have developed in their minds what the stereotypical Superman is.
They don't know or care that there are many versions of Superman in the comic books. Snyder's Man of Steel is based on the comic series Man of Steel, that was written by John Byrne.
