I am inclined to believe that the "critics" watching this film (and perhaps some of the viewers) aren't thinking realistically about the genre, and the movies that Need for Speed pays homage too. I suppose I can't blame the general public for considering this as a video-game film, it is that on the surface. Yet, the real stunts, the Shelby GT and the special attention to cinematography are art in their own form. The director - a stuntman himself - clearly watched Hal Needham (and Smokey and the Bandit) closely. Interesting how Smokey was second to Star Wars in '77, yet Need For Speed is critically-slammed. Smokey definitely did not have a Shakespearean plot, and yet, many would argue its importance.
As a car-lover, and a film-lover, I love Need for Speed. Give it a chance.
