WHY DOES EVERYONE ALWAYS COMPLAIN about Hollywood’s propensity for sequels? Sophocles and Shakespeare seemed to do OK with them, and the “Thin Man,” James Bond and “Mad Max” movies prove that there’s a lot of life in the genre.

No, the problem in sequels is not in their existence, but in their execution: Most follow-ups are too similar to the original (“Rocky” II through V) or too dissimilar (“Grease 2,””Alien3″). Hollywood is missing the point.

In the ’40s, Universal noticed that two of its franchises, the “Frankenstein” series and the Abbott & Costello films, were running out of steam. So some executive came up with an idea so simple and so brilliant that it’s staggering: combine the sequels.

Just imagine it. Those nice guys from “Grand Canyon,” Kevin Kline and Danny Glover, hurtle into the tow truck to help Susan Sarandon and Geena Davis and their banged-up Thunderbird at the bottom of the canyon. The women finally find the sensitive men they’d never known, and the audience gets “Thelma & Louise’s Excellent Adventure.”

Joe Pesci confronts the killer alien as “Lethal Weapon IV” meets “Predator 3 .””Broadcast Newsies,””Last Tango of the Mohicans,””Malcolm, Exorcist.”

Writer Aaron Sorkin knew this when he combined “The Caine Mutiny,””Sgt. Rutledge,””The Court Martial of Billy Mitchell,” et al. with “Top Gun” in his totally original “A Few Good Men.”
