The real problem with Man of Steel (and the other DC movies really, is that it is a DC movie.
A large, or just vocal, number of people seem to only want Marvel movies and will immediately decry any non-Marvel movie as absolute shit the minute it is announced while simultaneously defending every Marvel movie with equal ferocity.
Civil War had just as many flaws as Batman v Superman yet the Marvel movie is, for some reason "The greatest Comic Book movie ever" while the DC movie is a worthless pile of shit barely better than a Paulie Shore movie.
Suicide Squad was denigrated at every step of the way and Wonder Woman and Justice League were already being called failures before production even wrapped.
And at the same time Marvel is forgiven for every weak villain, low/no-stakes fight or failed attempt at an emotional moment.
Spoiler for Civil War
