Great show. The difference is that they mostly pay attention to the details and try to make those details believable. The most glaring exception is an action sequence is in the 9th episode when the car is intentionally crashed off an overpass. I do not know how a sedan traveling at speed, spinning, and driven off a 30 ft overpass can land on its roof and all walk away with minor injuries.
However, the show does much better than others at making the action sequences mostly realistic. Very good show and looking forward to Season 2.
