At least CitW had an original idea and intriguing design. It doesn't jump out and say 'hey this is a horror movie', but at the same time the bizarre set up of the house and the absence of anything else around it make you uneasy, as a horror movie should.
Your other two examples however... sheesh! Look up 'subtle', guys. Throwing skulls and bloody knives on your poster does say it's a horror, but it does not MAKE IT a horror.
