I was pretty underwhelmed by House on Haunted Hill. It's well regarded and that actually works against it. For a genuine haunted house, maybe try The Haunting of Hell House. Terrific movie that the big twist at the end almost ruins.
Go see Night of the Demon or Curse of the Demon, whichever you find. They're the same film, under one title in Britain and the other in America (and it still hasn't been standardized!)
