Nicolas Cage and Diane Kruger in National Treasure: Book of SecretsNATIONAL TREASURE: BOOK OF SECRETS

National Treasure: Book of Secrets, the follow-up to 2004's globe-trotting-archaeologist adventure, could generously be termed "perfunctory"; it gives (family) audiences exactly the formulaic, Indiana Jones-lite action, romance, and humor they adored in the original. It could also, less generously, be described as "crummy," as returning director Jon Turteltaub ensures that every remedially staged sequence has the same bland, going-through-the-motions tone as the one that came before. (At least its predecessor provided a few jokes.)

Samuel L. Jackson in Snakes on a PlaneSNAKES ON A PLANE

Incessant buildup for a potential Hollywood blockbuster is nothing new, of course. But in the case of Snakes on a Plane, it was the nature of the buildup that proved fascinating; everything hyped about this cheesy scare flick - the hysterically candid title, the presence of Samuel L. Jackson in bellowing motherf---er mode, the re-tooling to secure an R rating from its original PG-13 - seemed to promise, "This movie is gonna suck, and you're gonna love it." Offhand, I can't think of another movie that was so aggressively - one might say honestly - marketed as the schlock it was almost certain to be. By the time the movie opened last Friday, the anticipation among connoisseurs of cinematic crap had reached such a fever pitch that nothing less than the Best Bad Movie of All Time would do.

Perhaps unsurprisingly, Snakes on a Plane isn't the best bad movie of all time. But it'll still do.

Anna Faris and Drew Mikusa in Scary Movie 3SCARY MOVIE 3

With Scary Movie 3, the assignment of directing has been passed from Keenen Ivory Wayans to Airplane!'s David Zucker, which is a big step forward right there. (Zucker isn't much of a director, either, but at least he has ideas on how to shape a scene, and is actually pretty adept at making his film parodies look like the films they're parodying.) Plus, any time Zucker and company are satirizing the outrageous pomposity of M. Night Shymalan, whose Signs receives - and deserves - particularly harsh treatment here, Scary Movie 3 is everything you want a movie spoof to be: smart, funny, and more than a little mean. (And heartening - until now, I thought I was the only one who detested Shymalan's "Hitchcockian" appearance as the vet who accidentally kills Mel Gibson's wife in Signs.) The wide-eyed, appealing Anna Faris returns as the lead, ably satirizing Naomi Watts' reporter from The Ring, and comic actors such as Charlie Sheen, Jeremy Piven, Queen Latifah, Camryn Manheim, and legendary spoofster Leslie Nielsen all score some laughs. So why is Scary Movie 3 still so disappointing?

Penelope Cruz and Tom Cruise in Vanilla SkyVANILLA SKY

Vanilla Sky could be subtitled Jerry Maguire Climbs Jacob's Ladder to Reveal What Dreams May Come, and if that's not enough reason to run for the theatre's exits, the movie's actual presentation should be.
