IMHO, this is still the best MCU stand alone character films with some of the best action scenes in the entire MCU. Two scenes in particular get me every time I see them: the racing scene with the suitcase suit, then the “kill zone” battle with Iron Man and War Machine just absolutely wrecking the scenery. I still remember how awesome the big mini gun sounded in whatever theater I was in, either IMAX or Dolby Digital.
