Just finished watching it tonight and I did enjoy the series, but.....
It really could have been made by the 'Retirement in India' tourist board. Everything was about niceness, serenity, spirituality, cheap cost of living etc. and it made living in India look like a no-brainer.
We didn't see any beggars following you for hours at a time, we didn't see it being like living on a rubbish tip for miles in any direction, people pissing and shitting up any vertical surface, wrapped up bodies by the roadside. Everyone bothering you for money and trying to rip you off.
It was a bit like one of these programmes that makes out you can break down somewhere in rural France and the whole village turns out to bring you bread, wine and cheese. Whilst some moustachioed mechanics in blue boiler suits mend your car for nothing before offering you a bed for the night.
India's interesting, and everyoen should see it, but I don't think the reality of moving there will be anything like what was shown.
ETA: One thing that I did enjoy about it was that the people selection was just a bunch of nice, normal people. It stayed all about their experience in India (apart from maybe Jan going on a bit about being the world's loneliest woman) and wasn't about who would have an argument with who, fallings out, etc.
