I can't help but be disappointed that they aren't going to do all the two-parters as separate feature length editions. In the way they came out on video and DVD here in the UK.
You know, even if it meant they had to double-up per disc.
"Time's Arrow" back-to-back was a favourite of mine.
But having so far had to import "Redemption" & "Unification", I suppose the writing's on the wall for anything other than the season sets.
