I'm not too sold on what DC is doing right now. Other than the Dark Knight trilogy I can't remember DC doing any movies that have impressed me. I wasn't a big fan of the man of steel and the new batman trailer gives me Zack Snyder vibes which means a mediocre in your face action movie that will leave me wondering how soon until it's over (dawn of the dead was alright).
I had some small hope for suicide squad but this kind of rubs me the wrong way. I guess it's a different take on the Joker so we'll have to see how it turns out.
In short, I'm very skeptical.
