I finally received the Blu-ray set from A&E this past day (Wednesday) and I started looking at the discs as soon as I got home from work. (After 9pm, and after walking the puppy).
I immediately noticed a jaw-dropping upgrade in picture from the DVD sets I enjoyed 10 years ago. This is literally a night and day difference in picture quality. Also noticed that the 5.1 sound is actually pretty effective.
For this review, I will be comparing the new Blus to the old SDs, switching my HDTV input between a PS3 for the Blus, and a Pioneer DVD/laserdisc player for the SD discs. I will also include the revised transfers of three episodes on the Bonus Disc in this comparison. I will also compare the transfers between the UK Blu-ray set and the US Blu-ray set, to confirm that they are the same. From all the Network and Granada logos I am seeing on the discs, I will be shocked if I find different bitrates, codecs or anything else.
I watched the opening teaser for "The Metamorph" on the fifth disc, and noted a definite upgrade in picture from what I had seen on the SD DVD, although not as dramatic as the Series One material. I didn't really have a problem with the 2.0 sound. But I haven't done a direct comparison yet.
Watched the "These Episodes" collective featurette for the new episodes covered, and found, particularly in the case of "Another Time, Another Place" that there were more interesting comments available. Johnny Byrne openly acknowledges the dream logic factor in understanding and in appreciating the Series One episodes. Byrne has nice and appreciative comments about director David Tomblin (who would go on to be an assistant director on some major Hollywood productions afterwards)
Also watched the interview with Sylvia Anderson. The early sections (which I think A&E initially intended to edit out of this Blu-ray, and then changed up and left in) have nothing to do with Space: 1999. They cover other productions like UFO and The Protectors. The Space: 1999 section is primarily devoted to Sylvia's disdain for Martin Landau and Barbara Bain. Sylvia describes Martin Landau in decidedly uncomplimentary terms. She also proudly recounts a moment where she declined to return a phone call from Bain years after the series was over, since Bain and Landau never called her during the second series. Her discussion here is along the same lines as her "Testament of Arkadia" commentary from the SD Bonus Disc.
Overall, this is a really, really nice package. It's truly a gift to US fans of this series - providing the best transfers anyone has seen of the episodes, along with just about every extra enjoyed by UK fans five years ago and previously held back from the US. If you love or even like this series, and you have a Blu-ray player, this should be a no-brainer purchase.
And yes, A&E misspelled "Testament of Arkadia" on the 5th disc. It doesn't change the contents, which include a lovely transfer of that episode.
