All three of them have flaws. Still, I respect the youngest sister the most because she's clever and she stands by her principles. I think she's a bit too strict and stubborn at times but it's being honest to herself and her morals so I love her for that. I absolutely adore Leila's character and her acting. Too bad she didn't end up with Jack and had a horrible and unfair ending. The eldest sister is way too sacrificial and thoughtless that I got a bit annoyed even though I know she's a very kindhearted person. And obviously, the middle sister is manipulative and totally wicked and I absolutely hate her. However, Louisa So did a GREAT job portraying her character.
i like the small one cause shes smart in trying to find out everything and in the end she was smart to write the name with blood (;
omg.. definitely not the middle one, the big one is sorta retarded, and the youngest i feel poor for her though
