Christ you just need Aberdare and you've got the 'lived in shittest places' badge all sewn up!
I can think of so many more worse places than any I've listed.
What's wrong with Sutton, I was only young but I remember it as a pleasant enough town. Milton Keynes was a bit soulless, but was a clean and modern place to grow up. Wigan is an awesome town. Full of northern, working class charm, and halfway between Manchester and Liverpool. It was a great place to be a young, single bloke in my 20's. I really miss living there. The IOM is also a great place to live. A bit quiet for some, but then I've got a young family, so it's brilliant. Beautiful scenery, hardly any crime, and no traffic. At the moment, I wouldn't live anywhere else.
