The genres you list are very popular in the English world. It's fine of course but to use that to argue for a supremacy of English language literature doesn't strike me as a very solid argument. It would be like saying that Comics are superior to Bandes Dessinees because you enjoy super heroes a lot. Or that American cuisine is the best because you love hamburgers, tex mex and slow cooked meat. Nothing wrong with that but it's very subjective.

The American cultural machine is also incredibly powerful so it can impose its themes everywhere around the world, which also leads to this optical effect, you end up using it as the yardstick to judge everybody else's cultural output.

Beyond that I find this entire thread discussing the potential superiority of English literature frankly odd and rather meaningless. Anybody who can take English, French, German, Russian, Japanese and, say, Chinese literature and pick a winner is frankly an idiot. How can you even begin to judge something like that? We're talking about centuries and centuries, thousands of notable writers, millions of pages, hundreds of genres, from poetry to plays to novels to biographies. Who wins, Jacques Prévert or Tolkien? Yukio Mishima or Isaac Assimov? Mikhail Bulgakov or John Grisham? Fernando Pessoa or JK Rowling?
