I'm two episodes in, I'm quite enjoying it, but the flaws are glaringly obvious. I'll start with the biggest one and that is the supposed gap in decades that has occurred. I would have much preferred that it was set in the 90s or early 2000s, with the first series being set in the 70s this just doesn't add up for me. I'm finding it hard to move past it and very distracting.
The second flaw is the constant nods and winks to the younger generation and references to Instagram etc. There was an annoying pause in the flower shop when a customer paid for his purchase using his phone. This approach, which I think is intentional, is incredibly obnoxious.
Aside from these criticisms, I'm still a fan of the original material, and I am hopeful it settles down. Laura Linney rocks
