This giddy summer extravaganza does deliver aerial thrills with eye-dazzling visuals and ear-smacking (though beautifully designed) sound.

If the Navy is looking for splashy recruiting tools, it could do worse than Stealth, a zillion-dollar action movie stuffed with futuristic jet fighters, glamorous carrier pilots and an overload of explosive, mostly digital derring-do.

A sort of retarded "Top Gun," Rob Cohen's Stealth revisits the world of cocky fighter pilots and war games turned real, but it has some serious moral quandaries on the brain, and too much thinking gets it into trouble.

Even Cohen can't dull the loony romanticism of the movie’s finale and, to his credit, stages one truly spectacular bit of action midway through, when Biel bails out behind enemy lines and narrates each harrowing moment of her earthward plummet.

Though Stealth's strengths are obvious -- high-tech marvels and a good cast -- so are its flaws. At its worst moments, a mad robot seems to have taken over the movie, too.
