I LOVE these movies. I probably have seen the uncut BVS almost 25 times.
As a person who never read comics, I had no preconceived notions other than stuff I saw in previous superhero movies.
This, for some was nothing short of a bastardisation (sp?)of people's most beloved characters.
For me, I love this Superman. I LIKE the grim,gloomy guy so far. His life has been pretty emotionally torturous. But, I always thought Snyder did this so there would be more of a payoff.
It may be nothing like the comics but I don't find a thing wrong with the story or acting.
I mean, in every movie maybe you can pick something else someone would do or say or .. whatever. But I just don't have any preconceived notions other than what a trailer shows( which I've often successfully avoided. It's tough to stay away.)
