Earlier quoted context omitted.
I speak 4 languages and have read literature for 3. The depth and diversity of modern english fiction has no parallel, at least for the genres I enjoy(sci-fi, fantasy, alternative history, thrillers).
What is your native language? Mine is Polish, for sci-fi I could not enjoy Stanislaw Lem translated to English. On the other hand I really enjoyed translation of H.P. Lovercaft to Polish. I find Douglas Adams "Hitchhiker's guide to galaxy" lot less funny in Polish. There was also really bad (in my opinion) translation of "Lord of the rings" to Polish which tried to translate proper names, but there was different one…
You are right about translated literature, though that was not my primary point.
