Reading about the scheduling issues during 2 and 3, I'm kinda glad I waited for the DVD sets. By the time I am done with 3 and what's aired of 4, I should be all caught up for the finale.
Today's buys:

Image quality is good, though it's obviously not using as high a bit rate as film transfers. There's a smidgen of image noise, and for whatever reason, certain scenes in one particular episode (the Sun + Jin ep. Like ep 2) were of lower quality. Still HD!

Want to know why There Will Be Blood sucks? Because even Juno managed to pull an HD release.

A Patel recommendation. Luc Besson is crazy hit-or-miss, but at least this promises to look really nice.
