Just a heads up, that tonight’s (Saturday, May 29, 2010) rebroadcast of the LOST finale (6×17-18 “The End”), which just started a few minutes ago on the East Coast, is one of those “enhanced” episodes with the pop-up hints.
5/31 Editing to add: The enhanced version of “The End” is available on Hulu (scroll down — it’s underneath “Episodes” and “Clips”).
