Here's the thing most people see this trailer and go ok its different and could be good but I'm kinda skeptical. Personally I'm a comic book fan so I am genuinely excited.
DC fanboys look at it and... "OMG THIS IS PERFECT IT IS SOOOO MUCH BETTER THAN ANY poo MARVEL HAS PUT OUT I AM SERIOUSLY SHITTING MY PANTS OVER HERE IN ANTICIPATION FOR THIS MASTERPIECE"
Basically if you're not a fan boy and you're just a comic book fan you're cautiously optimistic. If you're not a fan boy and not a real comic geek you're seriously worried (just look at the reviews of the teaser.... I can't believe that's a thing but it is)
What cracks me up is DC fan boys still poo all over Marvel specifically the Avengers. The first Avengers was an amazing movie and was almost perfect. Basically everything that has been said about AoU says it is going to be the best Super Hero movie ever from critics mind you not fan boys. And the trailers have done nothing but back that up...
Yet DC Fanboys still poo all over it worse than Panthers fans do someone who questions Cam.
