There's a lot of times in this movie when you're like hmmm..would that really happen like that? And there are other times when you aren't sure if the antagonist is even totally that bad - so this was frustrating at first, but once you kind of give in to it, you see that it's pretty clever after all. I like the performance by the lead actress a lot - she grounded this otherwise farcical, far-fetched movie (I mean, why would people buying a house care about who lived there before / if the deck was finished???) -- anyway, the end was pretty sly and well done too.
