Actually, I found the whole programme rather boring.
I do agree to a point
I found the first half very slow going. Whilst grandad and his ambulance career in the war was interesting it seemed very repetative, he seemed to say the same thing (grandad saved many lives, etc) over and over again. This could have been condensed.
The Indian half was a lot better, but I just hate the assumptions !!! (that seem to be in all the episodes)
Because the indian connection was not found in one generation it was assumed that it must be the mothers side a generation further back - why not the other line? I think they did this a couple of times, just ignored the fact that someone had two paretns and followed just one of them looking for the Indian connection. OK they knew the end result ... but not a good example.
