Cavill's Superman was written in a way ( to me ) that he came off as a standoffish God.
He had none of the "Aww shucks" personality from Smallville. The charm that we associate Superman having since he was raised there.
He came off as ultra serious 95% percent of the time.
I understand you have to modernize films/characters, but in this case, if it ain't broke don't fix it.
Snyder tried to reinvent a perfectly fine wheel. What we got in result was a octagon wheel.
Captain America did just fine with his boy scout attitude.
Spiderman did pretty ok with his personality also.
Both were true to their comic roots.
You have to look at the whole body of work in the comics and not just the last 10/15 years.
I can almost guarantee if wb would make a Superman film based on birthright and Superman for all seasons, Bring back cavill, hire Brad Bird to direct, then it would make close to a billion if not more.
We do not want an edgy, mopey, dark, too cool for school Superman film. We just don't.
He needs to be hopeful, with a sense of humor, has the "I'm from Smallville Kansas" personality, he loves his powers, and he loves people.
Stopping a purse snatcher to him should be just as important as saving a crashing plane.
No job is too little or big.
