Ben, heres a review for the lost blu-ray.
http://bluray.highdefdigest.com/915/lost_s3.htmlPerfect. Stunning. Amazing. Those are just a few of the words to describe the video quality of this 'Lost' Blu-ray set. The 1080p/AVC MPEG-4 transfers exhibit a breathtaking clarity and detail far beyond anything possible on standard DVD, and even significantly superior to the show's 720p broadcasts on the ABC network. Presented in the 16:9 aspect ratio of the episodes' original HD airings, the image is extraordinarily sharp, with no distracting edge enhancement or digital compression artifacts. Every blade of grass on the island, every stubble in Jack's beard, each one of Kate's freckles, and all the skin pores of every actor are visible in striking detail, even in medium and long shots. Colors are vibrant and bold. The contrast range is crisply delineated from inky blacks to bright whites, with an exceptional sense of depth in every scene.
A minimal amount of film grain is present in some scenes, but it has been well digitized and compressed to retain the proper film-like textures without looking noisy. The show has outstanding, feature film-quality photography and lighting, and all the lovely island scenery certainly helps to make 'Lost' the best-looking series on television, and now one of the best-looking releases in all High Definition media.
Note that as the show's opening title flies past the screen, the brief bit of artifacting visible on the letters is a flaw of the title animation itself, not a problem with the disc transfer. That issue has been present in every network broadcast and DVD release.
