Man of Steel is by far one of the worst movie going experiences I've had in recent memory. Taking away from everything tied to Superman, it's poorly written, poorly directed, and has performances that range from over the top to completely dull.
The main problem with Man of Steel is that it wants to take a more dark and serious approach with the character, yet the filmmakers arent competent enough to stray away from the standard hollowness and stupidity you'd find in any generic blockbuster. That clash results in a slog of a film that's equal parts dull and unintentionally campy.
For all of Snyder's talk of making Superman relatable, the film constantly pushes him away from mankind, observing him from the perspective of other characters like a germ in a petri dish. He's constantly exposited to, and rarely has a word to say, or a decision to make on his own. If not for the discovery of the Kryptonian ship in the artic, who knows how long Clark would've been wandering aimlessly because he couldnt decide if he wants to follow his father's teachings or not. It didn't help that the interesting classic aspects of the character, such as his balance of identities and his relationship with Lois were either heavily subdued or completely removed. As a result, this version of the character is stale and boring. I would blame Cavill for an equally wooden performance, but with the material and direction given, I cant blame him.
The perfermances all around are as dull and lifeless as the material, with the exception of Michael Shannon, who hams it up to 100. There's so little humour or fun to be had in the script that any attempt at doing so feels forced and out of place.
I dont believe in Lois and Clark's relationship, when there's so little chemistry and dialogue between them. I dont believe in Clark's connection to humanity when he's shown to be either pushed away or treated like crap by them his whole life, and vise versa. I dont believe in the world ever accepting this character when his very existence nearly caused the end of the world.
Snyder and Goyer handled these serious, compelling ideas with the depth of a puddle and the subtlety of a sledgehmmer.
No image better showcases how wrong those involved were for handling such complex concepts than this one shot in the film:
