A very well made, disorienting movie about inarticulated despair and utter hopelessness. It reminds me a lot of ''Over the Edge,'' Jonathan Kaplan's bleak, bitter picture of teen-age life in an architecturally perfect, California housing development. Unlike ''Over the Edge,'' however, The Boys Next Door is less interested in causes than in effects, which Penelope Spheeris, the director, turns into the photographic record of a grim, vivid, joyless ride to hell.
