The extras on the Lost DVDs haven't been good since season 1. The best extras on this DVD were the mobisodes, the 'Lost in 8:15' segment and the faux-documentary 'A conspiracy of Lies'.
As for the eps, good to see them again and I liked seeing the extended press conference scene. It's so good.
I love the theme on the spine art of the boxets. Season 1 was Jack, Season 2 was the island, Season 3 was the Dharma logo and Season 4 is the helicopter. Very nice.
