The DVD releases of these films (the 4 volumes) with the individual thin cases, even with the stupid mixed-up ordering of which movies were in which sets, were far better.
What you get here are two beautiful hardcover books with cardboard pages. Each page (verso/left) contains a collage of imagery from the two films/discs on the opposite (recto/right) page. It's odd having a hodge-podge of two films... it definitely would have been nicer if each film got it's own artwork. Also, like another customer mentioned, we don't get any fact-sheets... or any text besides the film's name printed on the discs. I really miss my brother's DVD sets.
Also, I'm disappointed that they didn't bother to re-author the Blu-rays. All of the movies that were previously released on Blu have identical discs. The major problem here is that the video compression was, and still is sub-par. If you have a great TV, you'll definitely be able to see the compression artifacts on the majority of these films.
Casino Royale and Quantum of Solace stick out because their disc content match that of their previous one-disc releases... they didn't bother to re-author the discs to give us a unified experience. Overlookable, but worth mentioning.
Quite sadly, all those movies that were previously unreleased on Blu-ray didn't get the full upgrade to HD... in terms of special features. All of the classic films have amazing making-of documentaries. The ones already released had upgraded HD documentaries. The documentaries featured on the discs previously unreleased are all in SD at 4:3, so all the footage they show from films are letterboxed & pillarboxed on widescreen TVs. It's a shame.
They left a slot with a fake cardboard disc for Skyfall, which is cute, but impractical. If they release Skyfall on a one disc, they'll be making a huge mistake. Not having a second disc dedicated to bonus content would be ridiculous... but a two disc set would render this slot, essentially useless.
If you haven't bought any of the films yet, or you've bought them and you're considering replacing them with this, I'd honestly consider just recommend waiting for the previously unreleased films to be released individually. If you like Casino Royale, buy/keep your 2-disc special edition!
So, overall good, but would have been perfect with better packaging highlighting each individual film (and possibly trivia), with re-encoded videos of higher quality.
