I also prefer the original versions, although I only recently managed to see the original star wars version (no damn DVDs for YEARS, mister Lucas !) and the one voice that is actually better in French is Yoda's... it suddenly sounded so WEIRD in english, like some weird alien squeaky thing, whereas the french voice sounds like a venerable old monk which seems more fitting to me...
But all this has nothing to do with the topic, so I'll just go away
