The first half of “Weird Science” (1985) is so good – classic teen comedy from writer/director John Hughes – you forget how badly the second half runs off the rails. Rejects from “Mad Max?” Cruise missiles? Bill Paxton as Jabba the Hutt? Granted, the ship rights itself for a semi-sensible ending that’s a cross between “Risky Business” and “Sixteen Candles” but you’re left wondering what could have been. Anthony Michael Hall and Ilan Mitchell-Smith are classic high school dorks who use early computer technology to build a beautiful woman (Kelly LeBrock) for immoral purposes. She ends up teaching them a valuable lesson.
