This is Spinal Tap is so inescapably rife with over-the-top zaniness and gleeful, knowing stupidity. But for all its exuberance, what’s most astounding about this concoction of sugar and spice is how easy-going, relaxed, and even lethargic it is. The tone of the film conveys a sort of laid-back afternoon, with sly, subversively restrained performances complementing characters rather than stealing them and running away with them. This is not one of the many throw-shit-at-the-wall-and-see-what-sticks-films becoming popular around the time of this film’s release; it’s a comedy with a difference. The batting average for jokes is remarkable, with each one seemingly assembled with care and craft. It is a thoroughly composed, careful, willful, and even delicate motion picture, and it is one of the sharpest comedies ever released.
