Revisiting last spring’s two-hour “Lost” season finale (tonight 9-11 on ABC/7) isn’t the only way to catch up to the show’s goings-on before Thursday’s 9 p.m. fourth-season premiere.
If you haven’t already run across the web’s ubiquitous “Lost in 8:15” (also downloadable free at iTunes), it’s worth that much time to watch a recap of the previous three seasons’ main plot points. They’re narrated almost hilariously fast and with dry dollops of wit, but they certainly do the trick.
There’s also Thursday night’s 8 p.m. ABC special “Lost: Past, Present & Future,” promised by the network to “relive their story of survival to prepare for the shocking Season 4 premiere that will change everything.” And of course, those with hours to spare can watch full hour installments via DVD, download or ABC.com’s free streaming episodes, all three seasons’ worth.
