Mostly I agree with this, but for animated works dubs can be an integral part of the product when done right, and some are even tweaked for different languages (although I strongly reject adjusting the actual cultural content for different locales). The dubs have to be made in concert with the original though. There is also a lot of plain crap out there. But absolutely; for anything featuring live action, dubs just damage the original. I watch a German man building his massive Lego city on Youtube (narrated and recorded quite professionally) with my five year old son for a few minutes before bed. He is now at the point where he is trying to give this weird language (to him) a place in his head. Some words are familiar (being Dutch), some are foreign, and you can see the feedback loop happening when words do land; he wants to know what that man is saying. I don't except him to pick any German at this point, but the basics of immersion in another language are there.
