I did his Himalayas, but none of the others. Thanks for the suggestion - I'll give them a go.

Yeah, definitely need to start at the beginning of season 1 to avoid various spoilers.

It's interesting because (unlike most movies) they had actual security consultants and use real-world tools and techniques, but without it being tedious (thought a couple of times I did feel it a bit name-checking/buzzword bingo).

Heh, yes, definitely. But it is fun though.
