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.
