But this is the world of John Hughes, and it's best not to ask questions.

The script is inventive and the payoff is worth the wait, and Hughes has mercifully stayed away from the excessive vulgarity that marred "Uncle Buck."

Columbus' direction of the physical comedy is well-timed, though his speeded-up camera for the early chaos at home seems ill-advised. John Candy's cameo, which seems largely improvised, is not funny. And John Williams' sweeping score is more suited to an outdoor epic than an indoor slapstick comedy.

The performances are very good, especially by young Culkin and Pesci and Stern. And special kudos to Roberts Blossom as the supposed "snow shovel slayer," who takes one sentimental scene and gives it unexpected depth.

Ultimately, "Home Alone," rated PG for comic violence and a couple of mild vulgarities, is a kids' picture. And kids are going to love it.

If you're a kid, by the way, bump up the old-fogey 21/2-star rating to three.
