Effect(s) without cause is generally not possible in the real world but in the world of Hollywood remakes, not only is it possible, it's required. The Haunting has been given the computer treatment courtesy of a 1st-class cinematographer-turner-director who once showed promise (Jan de Bont- Speed) but has since produced a string of big budget garbage (Twister, Speed 2).
Actor are superfluous in a movie of this type and they seem to realize it. Liam Neeson and Cathrine Zeta-Jones act like they wish they were anywhere but in this film. Lili Taylor makes an attempt to add something to the proceedings but whatever that something might be is unknown since the script feels like half of it is missing. Events just happen, good and bad ghosts show up with no rhyme or reason and then the story just ends with a most unsatisfying non-event meant to wrap up the previous 90 minutes of inanity.
There really isn't even reason to see this for the effects since we all know that anything can be put on screen now. Why not watch effects in the service of a good story instead of just for their own sake?
