Even presented on 38 discs (36 on Blu-ray), ABC's classic series will never be "complete." You could teach a polar bear string theory before you connect all the dots here. Extras include a great documentary about the hatch and-salivate, Lost fans!-a brief, brilliant "epilogue." Ben (Michael Emerson) returns, smiling in a peach-colored suit and offering details about the Dharma Initiative. It's surprisingly light, even goofy.
