I finally watched Batman V Superman(Ultimate edition). I think Snyder's greatest obstacle is that he misinterpreted the character. Perhaps he had wanted to subvert the audience's expectations with his rendition. Unfortunately, I don't think the material quite lands. A lot more questions are raised than Mr. Snyder cares to answer and this leaves one with the sense that the questions were either unintentional or inserted for the sake of creating an air mystery where none was needed.
Why is Wayne Manor abandoned? It is key to the mythos of the Batman character in nearly all interpretations of the character. Almost a character in itself. While Mr. Wayne and Alfred have always been criminals this has always been in reference to the law(breaking and entering, vigilantism, etc). Here it seems Bruce embraces criminality as a philosophy. Why is Batman afraid of Superman? In the source material he is afraid of Superman's power. He is not afraid of being killed by him. Bruce has always embraced his own mortality. His greatest fear is that he will fail Gotham and thus also fail his parents. When did Batman embrace live rounds in Mr. Snyder's rendition? In the source material when forced to use ammunition he uses rubber bullets. While being on the edge of becoming a murderer, Batman did not kill the Joker, Joker snapped his own neck to prove a point.
Additionally, I think Amy Adams' Lois Lane and Jessy Eisenberg's Lex Luthor were horribly miscast. Miss Adams' performance attempts to give gravitas to a role that doesn't have much. Eisenberg on the other hand is simply not Lex Luthor. The words coming out of his mouth are right but his mannerism and characterisation imply he is an imposter who has only read footnotes about Mr. Luthor. He lacks the flare, charisma and drive that the Luthor of old has.
While Mr. Snyder has injected some of his signature camera work into the final product, a lot of it seems devoid of meaning. Cool shots that portend to a deeper symbolism but lack the substance to support the portrait being painted. Preceding shots don't seem to lend themselves to any deeper visual story telling that would help decipher the symbolism of the cooler follow up shots thus they end up being all style and no substance.
