Honestly, I can't say this bothers me all that much. The new shot looks realistic, so it doesn't jump out or distract from the movie as do, say, rontos in ANH and the Fraggle Rock sequence in ROTJ. No one's character is affected, it doesn't seem out of place, and it's not jarring. I certainly agree that it's an unnecessary change, but I don't see how it's a major detractor from the film. Frankly, I don't think I'd have ever noticed it if I was just watching the movie through.

While I concur that it's a bit disturbing to see this classic tampered with, I haven't seen anything too damning thus far. When the Arab swordsman shoots first and a CGI Moses appears next to the Ark, then I'll join in a boycott. At present, such a notion seem unjustified to me. :)
