At its best, Lost is a delicately layered adventure, laced with some stand-out moments. You'll find ample instances of them here, as well as umpteen examples of the quality of writing that underpins the show. Far fetched? Yes, occasionally, and you could also argue that it takes a while to recapture the energy of those dramatic opening episodes. But this is still a lavish, compulsive show that benefits heavily from its clearly substantial production budget.

Naturally as there are more episodes made and planned, there are plenty of building blocks being put in place for later on, both through the evolving life on the island and the plethora of flashbacks that back it up. Yet it's at this point that the quality of Lost really hits home, thanks to lots of short term excitement with plenty still to enjoy as the show progresses. That makes Lost Series One a rewarding purchase, and one that promises even greater things ahead.--Simon Brew
