I think it's cool. Of course this site is Marvel fan boy central and everything about this film is reviled in accordance with what MovieBob tells you guys to think. There is no colour because they are going for an aesthetic tone, if you saw images from on-set there would likely be colour but they've gone for a very artistic style.
Who cares about high-heels breaking "realism" when you are watching a film about an orphaned alien from another planet and a man who dresses up as a bat and beats people at night?
But it's cool. I think it's good, there is room for a fun, over the top, colourful superhero franchise and a more drab, mature, and brooding one, because if DC wen for the exact same tone as Marvel they would also be accused of "ripping off".
Also Arrow is an amazing TV show, and Flash looks promising, hopefully they can both be in the Justice League.
