Seen em both. Really liked them.
WW is what it is. Action with a predictable plot, but its really a good movie.
Baby Driver is very cool. Not groundbreaking but intriguing and kind of different because of the quirky nature of some characters.
Your interest will be kept the whole time. Suspenseful because of the nature of his job but also because of the circumstances in the film.
Baby Driver on dvd? IDK. I dont think it would be the same. Still might be good but maybe not as good.
