My relaxation go-to is The Repair Shop. I love the (lack of) pace of it, and the only jeopardy being whether the owners of the restored thing will well up or not.

I've seen ads for Mr. Robot, and it looked interesting. I'll give an episode or two a go. Straight in at Ep01?

If you want an alternative for a nice relaxing watch, I'd recommend any of the Michael Palin travelogues. 

I've been working my way through them again and the Himalaya one is a particular highlight. 

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.
