Jan de Bont seem to have forgotten a well-known line in the movie industry, at least among great horror/suspense film directors: in a horror movie, it's not important what you see, but what you DON'T. All great horror situations, all possible eerieness, works better on the level of the imagination. So, it's much more a matter of creating mood than to just blow money spreading special effects all around.
The bed moves, statues moves, windows are alive, there's a wild 'féerie' of (supposedly) horror moments which turn to be not much more than a special effects showroom. In the end, the house owner's portrait is alive, and his ghost makes faces and roars throughout the place. What's that? Casper, the (un)friendly ghost?
Actors make their best to carry it on. Liam Neeson has virtually nothing to do. Upon the shoulders of Miss Taylor is the movie. Cathy Zeta-Jones embellishes things up. The blond chap tries hard to make his way out this movie, before he went out of his head (no pun intended). His headless final status is, itself, a good comment on this movie.
