Commentaries for season 6 on the complete blu-ray set?
I have heard that the complete blu-ray edition of the show has commentaries for season 6 which were not on the original release of that season back in 2013. I am in the UK and was hoping that these would also be added to the region B version of the complete set, but looking at reviews it seems that they don't have them, and that the commentaries must be on the US edition only.
I wanted to ask anyone who has the complete blu-ray set of the show from the US, if this set definitely does have commentaries, and if you think the commentaries are good enough to make it worth buying the region A set instead? I only recently got a blu-ray player so I don't have any of the seasons on blu-ray yet, just a couple on regular DVD, and I have considered getting the whole collection on blu-ray now that the show has finished. But it would cost a lot more to buy and import a region A collection than it would to buy a region B version from a UK store, so I would like to be sure that it would be worthwhile.
If the sets do have commentaries, I was wondering if they include much talk about specific themes of the season, like the idea of doubles and twins that seemed to be referenced a lot, and also things like the development of Peggy and Stan's relationship, and the ideas behind the Bob Benson storyline. Also, which episodes in general would you say have especially interesting commentaries? Thanks to anyone who can help with any of these questions.
