This is a jaw-droppingly good Blu-ray. The crispness of the picture and the richness of the colours is absolutely staggering. On the disc, I particularly like the way questions pop up at the end of each disc to make you think about what's going to happen. The SeasonPlay mode is a great way to drop in and drop out of the series, and the ability to watch all the flash-forwards in chronological order is a real treat for us Lost geeks.

As for the show itself; season 3 drew many detractors as it was unnecessarily long. An arrangement between the studio and the writers meant they finally drew a line in the sand and decided on the endpoint (at the end of season 6) which allowed this season to become tight and focused. New characters are introduced deftly and quickly become part of the fabric of the show without feeling like grating graft-ons.

A landmark show and this is the ultimate way to watch it.

A great season. Answers many questions but then open's doors to more. Brilliant qaulity on Blu-ray.

Lost series 4 is second only to the first series of Lost in my opinion. This is what high definition was made for, the island looks fantastic and the action scenes are amazing. The extras are also well worth a watch. Also, your looking at £60 if your planning on buying this on the highstreet.
