Compared to where? I guess San Francisco or LA or Singapore are more exciting and interesting than, say, Stevenage. And if you want white sand and warm oceans and coconuts falling off trees, then it isn't the place for you.
Personally, I think England (and the UK generally) is one of the most interesting places in the world. Of course, it depends what you find interesting. I love literature, art and history, so for me this island is a jewel. Bill Bryson said that in Britain, almost every square mile contains some amazing link to the past. Take Cambridge as an example. Every time I go there, I am amazed to think that Christopher Marlowe, John Milton, Isaac Newton, Byron, Wordsworth, Tennyson, Darwin, Nabokov, Wittgenstein, Stephen Hawking and Bertrand Russell were all students there, that it is the place where DNA was discovered and the atom first understood. Or take Oxford. Oscar Wilde, T. S. Eliot, Aldous Huxley and Evelyn Waugh all studied there, and C. S. Lewis and Tolkien used to read the Narnia books and Lord of the Rings out loud to one another in the local pub.
Like I said, I'm very interested in literature, so I tend to associate places with writers and books. To me, Bath means Jane Austen, the Yorkshire moors mean the Bronte sisters, London means Dickens and Blake, Stratford means Shakespeare, the Lake District means Wordsworth and Coleridge, Canterbury means Chaucer, and so on. Just recently I was mooching around London and happened to walk past the square in which Virginia Woolf lived and wrote. Almost every major figure in history seems to have lived or worked on this island at some point. Freud and Karl Marx are both buried here, Lenin lived here, and so did W. B. Yeats and Mozart. Even painters like Monet and Pissarro spent time here. The sense of cultural and intellectual depth is thrilling. Ted Hughes wrote about a pond, or something, being "as deep as England." It's a great line. England is deep; it feeds your imagination. It's just a shame we're taught to hate ourselves and our history. I've met several anglophiles who've emigrated here because they love the literature and history but are baffled by the shame and self-loathing.
