It was "okay". Frankly though, I found myself wishing he'd visited Sardinia alone; think it would have been a much better & more interesting episode, although I can understand the draw The Travel Channel figured re: adding his wife (since she's originally from Sardinia) & child.
For some vague reason I can't quite pinpoint, I found his wife annoying on camera, although their little girl is adorable. I was surprised that she was so blonde, when both mom & dad have black hair, but a geneticist I ain't, so who knows? Also found it odd that throughout the whole episode, mom is never seen even touching the kid - she's with daddy the entire time.
Regardless, I felt I sort of came away from it not knowing really a whole lot about Sardinia - unlike other episodes that always make me feel I want to visit the place. But since Travel Channel will - as always - start repeating this season's episodes ad infinitum in the near future, I'll have to watch it again & see if I come away with the same feelings.
