This film is terrible, it is like a student's effort. The budget is low.
Some spoilers follow.
The story is not credible, how could someone from USA experience things on events that happened in UK 10 years earlier, just doesn't make sense. The storyline that the husband drives his wife nuts using a partially staged sequence of events in a large country house but it is too disjointed and unpolished, just not believable. The acting (although the leads are hot!) is for the most part awful.
The effects are second rate and the "twist" at the very end which maybe is supposed to hold it together is just naff.
Not just my view by the way, look at other reviews on-line.
This is not even worth watching to experience a B movie, it's just at best second rate.
