That scene is amazing, and I can see why it's memorable - it's not just the simplicity, I think it's the organic nature of the set, too. Like in the LOTR movies, where you don't know that every article has been handstitched/carved/built, but it all adds up to a reality that CGI just can't touch. I'd much rather hear the thunk of something hitting a wooden table than the whoosh-bang of a big CGI effect.
