Maybe it's a mixture of all of those, yet whichever side of the fence you park yourself, Lost is undoubtedly an intriguing, and hugely successful, show. Its blend of past and present narrative continues with these episodes, and it's a loyalist and a half who won't admit that one or two of them are tepid at best. But there's some great stuff in here, with eye-opening character development, fresh discoveries and a superb end of season double episode that, in true Lost fashion, answers some questions and poses many more.

It's going to be a real challenge for the creative minds behind the programme to keep the momentum going, and surely the point will come soon where even more answers need to be forthcoming. But for now, Lost remains compelling viewing, and there's much to watch and rewatch in the episodes contained here. Even if it may drive you nuts trying to figure everything out… --Simon Brew

Synopsis
Created by successful television producer J.J. Abrams (FELICITY, ALIAS), LOST became one of the most popular and critically acclaimed programs of the 2004-2005 season. Utilising a ripe premise and well-drawn and acted characters, LOST attracted a huge following and was proclaimed the saving grace of a television year otherwise marred by derivative reality programming. The story concerns the survivors of a terrible plane crash, who find themselves stranded on a tropical island with seemingly little chance of a rescue. Medical doctor Jack takes a position of leadership, helping to rally the survivors and prepare them for a period of difficulty as they learn how to survive on the paradisiacal island. But everything is not as it seems, as the island offers potential danger in the form of a large, mysterious creature, and evidence is found that the plane crash may not have been an accident. As they struggle to survive, each of the characters forms alliances and makes enemies, all while dealing with the unresolved issues of the lives they've left behind. LOST distils the difficulties of society down to their essence, exploring these problems with compelling characters and with a setting that's equal parts paradise and mystery.
