The OTHER Sister (Spoilers)
I was surprised that the two sisters' storyline seemed to be left hanging, unless I just didn't understand it. I had to look up the plot on Wikipedia to check what was supposed to have happened - that the "old looking" sister had herself flayed in the hope of becoming young looking (I misheard the "younger" sister telling her that's how she regained her youthful looks, so didn't really know what her sister wanted the guy in the woods to do to her. I normally use subtitles but there WERE none on my DVD)
So then we see the "older" sister staggering towards the castle, apparently flayed (though she only looked very bloody - I would not have described her as skinned). What happens then? Does she confront her sister?
(By the way, I thought the "old" make up/prosthetics work was terrible - it was obvious we were going to see them transformed).
These were the only less than satisfactory notes in this great movie.
