(The full set is on iTunes USA for $59,99 & Dr. Strangelove separately in 4K for $14,99. Of course, you get the inferior Dolby 5.1 standard iTunes Sound with that)
Yes it’s faultless, a true classic. Off the top of my head I just thought of my five favourite films of all time in no particular order: 2001, Strangelove, Planet of the Apes, North by Northwest, Soylent Green. Two Kubrick‘s in there.
I bought the Blu-ray not so long ago so may stick to iTunes for this.
