What has been the biggest shock so far this season on Lost? Is it the discovery of the French woman? The death of Boone? Not even close... it's last night's return to the mainstream of Mackenzie Astin, the weenie kid from late-run episodes of The Facts of Life. I never thought his celebrity status could survive his starring in the train wreck that was The Garbage Pail Kids Movie, but 18 years after its release, I stand corrected.
