I've only been there once, but my impression of the place was not that great. London was a shithole (but no Brit will ever dispute that). The countryside was alright but even the suburban areas which are usually pretty wealthy in the US seemed pretty dreary and run down to me.
The people seemed sort of off. Not really rude or stupid, but just strange. It probably just has something to do with them being foreigners, but even a German or a Swede seems more similar to what I'm used to than an Englishman. I dunno. Also in Kensington Palace there was a pakistani guy ranting to a security guard about how much he hates America, which was pretty funny.
I r8 it 6.5/10.
