Well, I absolutely despise Man of Steel, and I’d rather watch Superman IV than endure that torture again.

I hate the needlessly dark atmosphere, it tries to be realistic while also being completely over the top and stupid.
The overt symbolism shows that Snyder is one of the most pretentious directors out there.
Henry Cavill is bland as bland can be.
Amy Adams is bland as bland can be.
Kevin Costner is bland as bland can be.
Russell Crowe is bland as bland can be.
Michael Shannon is over the top as over the top can be.
The colour palette is horrendous.
The camera work is horrendous.
The music is bombastic and bland.

That pretty much covers my problems with the film, though there are surely plenty more.

I award the film a two out of ten.
