I agree about Wan, for horror I always look forward to his films, he's very good. Well I thought Saw (the original one) was great, but didn't like Dead Silence I have to say, which was underwhelming. Insidious was a really good film though, I wasn't a fan of all the second half of the film but it didn't make me not like the film as a whole, and I think all the first half of the film, the real haunted house part, was perfect, I saw it at the pictures and I was genuinely scared, which doesn't happen too often. Seeing the reviews and general reception of The Conjuring has gotten my hopes up pretty high, it better be good!
Did you see Sinister? That's another one of the haunted house genre that I really enjoyed in recent times, it had its flaws but it did make me pretty uncomfortable at the pictures I have to say.
