Saw on Batman-News:
"What bothers me isn't the negative reviews, but how they amplified the negatives within the film. BvS is flawed, but it's not crap, or horrible. Most reviews have been vindictive in nature, rather than playing on both the positive and negatives, it was just another, "which critic can top the other with nasty reviews." I know some people will disagree with me, and state how they brought up valid points, but I disagree. There is valid points, but they're not that big, and most of the reviews nitpick the hell out of it. This movie didn't deserve the negative beating it receive."
On that note, here is a great new article posted a couple days ago.

These representations of these characters might not be the ones that fans want, but they are certainly ones that have been expressed in comics like The Dark Knight Returns, All-Star Batman and Robin, Superman: Peace on Earth, Red Son, and many other works like them. In the vast plurality of DC Comics there are many dimensions to these characters, and the interpretation put forward by Snyder in Batman v Superman is a heavy mix of these flavors with a cynical shot of Watchmen as a chaser. In Snyders version, negative interpretations of these heroes are not just possible worlds they are likely ones.
The opening of BvS painstakingly shows the impact of superhero violence with very particular 9/11-style image of Bruce Wayne running into the dust produced by a collapsed building, but the film also glorifies the same kinds of fights that it critiqued in its opening. The entire last twenty minutes of the film are the same kind of rampant, horrifying action that comprised the ending of Man of Steel, and a few scenes suggest a similar death toll the hands of the character Doomsday during its first energy-expending salvo. Many people have critiqued these final scenes for seemingly abandoning the opening lessons of the film, but I feel it is pretty clear that Snyder is pulling the old Watchmen critique here: if you want the spectacle, you have to deal with the consequences. You dont get your superheroes without their bad sides.
