Jena Malone and Laura Ramsey in The RuinsTHE RUINS

I caught The Ruins during a minimally populated Saturday-afternoon screening, so I pray that a larger, rowdier audience laughed like mad when our surgeon-to-be hero (the hilariously stalwart Jonathan Tucker) surmised the deadly situation he and his friends were in and barked, with absolute earnestness, "Four Americans on vacation don't just disappear!"

That poor, dumb kid. Never saw a horror movie.

Rachel Weisz and Ryan Reynolds in Definitely, MaybeDEFINITELY, MAYBE

If anyone's keeping track, writer-director Adam Brooks' Definitely, Maybe is the third romantic comedy of 2008 to climax with its protagonist taking a hasty cab ride to an inevitable romantic clinch and subsequent Happily Ever After. And that's about the only conventional element in it. I'm a little staggered by just how wonderful this movie is, as nothing about the film, from its cutesy setup to the presence of leading actor Ryan Reynolds, appeared to suggest anything more than the latest spin on a tireless (and, by now, tiresome) genre. Yet Definitely, Maybe is sensational, so smart and witty and refreshingly grown-up that, hours after seeing it, you may still find yourself in a great mood; the only times I stopped smiling at the movie were when I was laughing out loud.

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.
