Fast-moving fight scenes, outrageous auto antics and a sprinkling of ridiculous one-liners make “Furious 7″ a campy, crowd-pleasing escape. Never mind that the film repeatedly presents the impossible – a muscle car attacks an airborne helicopter – fans of the franchise know to suspend disbelief at the door. With nonstop action from start to finish, it’s easy – if a bit exhausting – to go along for the high-speed ride. Reality intrudes at the end: The film is dedicated to Paul Walker, who died in a car crash in 2013, and concludes with a montage of images of the actor from his five previous “Fast and Furious” appearances.
