Is everyone this miserable in the UK?

Was this film an accurate portrayal of your average Englishperson? Just about everyone in it was miserable. Brenda Blethyn as Cynthia must've set a record for amount of tears cried by a character in a film. England seems like a dreary place full of wretched people. I'm reminded of Ray Winstone's take on the UK after he moves to Spain in the film Sexy Beast:

People say, "Don't you miss it, Gal?" I say, "What, England? Nah. Fu*king place. It's a dump. Don't make me laugh. Grey, grimy, sooty. What a sh*t hole. What a toilet. Every cun* with a long face shuffling about, moaning, all worried. No thanks, not for me."
