I'm not sure if I want to buy the one with english subtitles or the one with english voices.
There were a few posts on this forum complaining about the English dub when it came out. (as far as i could tell they were posted by Czechs expressing their national pride) But, even though I don't speak Czech, I found that I agreed with them. It's such a lovely sing-song language, and the actors were so naturally emotive speaking in their native tongue, that it really gives that version more... "Umph" to hear the film in Czech.
So, in my opinion: get the version with the subtitles.
