Ok, while this does look fun, all the CG muzzle flashes, blood splatter, and whatnot robs ALL THE ENERGY from those fight scenes. A bit of a crossover from the Alec Baldwin thread, but you can't watch that trailer with all of its modern slick but souless choreography and just wish for real people to have to do that with real props, real action, and real practical effects. There is just a weight and respect that comes from practical effects that CG shoots right past, slicing 5 guys with CG blood and shooting another 10 right in the face with CG muzzle flashes has as much energy, gravitas, and thrill as watching 5 junior high kids dancing at a talent show compared to NFL cheerleaders at the super bowl. You NEED the visceral impact of a REAL WEAPONS firing, real people hitting and being knocked around, of REAL FLUID pushing out of tubes and squib packs drenching the camera in hersey goodness.
