Lethal Weapon 2 (1989)

But no, Lethal Weapon 2 is no artless, autopiloted waste of precious movie-theater air conditioning. It's fun stuff -- crackling, playfully escapist summer fare that doesn't make you feel taken advantage of later.

Lethal Weapon 2 is that rarity - a sequel with most of the same qualities as the original. I walked into the movie with a certain dread. But this is a film with the same off-center invention and wild energy as the original.

Before it skids out of control in the final sequence, the film is so careful to preserve its successful comic-action formula that it follows the most basic law of sequels. If you liked ''Lethal Weapon,'' you'll like Lethal Weapon 2; it's almost as simple as that.

Loaded with the usual elements, Lethal Weapon 2 benefits from a consistency of tone that was lacking in the first film. This time, screenwriter Jeffrey Boam and director Richard Donner have wisely trained their sights on humor and the considerable charm of Mel Gibson and Danny Glover's onscreen rapport.

The movie overall may be routine, but Donner gives it some spark and polish.
