Yeah I can imagine - although probably in any town you could go out and find a nice bit with nice houses and shops, and equally, you could find a bit where shops are closed and houses look a bit run down.

If I'm honest with you, I wonder if you need to think more critically about what you're watching? Grand Designs is designed to evoke envy (mostly) as well as some of the difficulties involved, which keeps people watching. I don't really watch YouTube but people generally seem more predicated towards watching things that evoke feelings of danger, anger, loss, worry, that sort of thing. In both cases you are being shown a version of the truth that results in the programme maker gaining somehow (money, views, whatever).

I'm only saying this off the back of your few comments here though, so apologies if I'm wide of the mark.
