“Need for Speed” is dumb and loud and sometimes technically impressive, which means that it is successful on its own terms.

Poots is a good sport and a deft enough actress to find the balance of silliness and gravity that the movie requires. Not that much, maybe, and she’s only allowed to drive once, but Ms. Assisting Tobey in his quest for payback - for vindication, redemption and the keys to a million-dollar European car - are (in order of importance) a lovingly modified silver Mustang, a wisecracking friend who can fly a plane (Scott Mescudi), two other wisecracking friends who can do other things (Rami Malek and Ramon Rodriguez) and Julia (Imogen Poots), a woman who knows something about cars.
