Personally that trailer didn't really jump out at me. It looked a little bland and the CGI seemed average.
One of my bigger concerns that I don't think anyone's mentioned yet is the colour pallet of the film. It looks like it might be that bland colourless looks that a lot of modern film seem to think is cool (I had the same issue with Total Recall). I hope they throw some colours in there.
Like many I'm not a fan of the black suit either. My main reason for this is he doesn't look like a robot in full black. He needs some metallic in there. Other than that I'm hoping there IS violence that at least makes it to the Bluray release.
