Because it looks terrible and doesn't capture the comic book magic that Donner's movies did. It looks campy as hell, as if Gunn decided to do the opposite of Snyder's Man of Steel, but with the same poor quality. And it has too many characters, it should've been named Superman & His Friends. Honestly, I have no idea why Gunn decided to introduce so many heroes in the first DCU movie. Does he not know how to make solo superhero movies?
Oh, and the actor just doesn't look like Superman at all! Christopher Reeve will always be the definitive Superman. The new guy just doesn't have that same charisma.
