A remake of the 1960 Castle film of the same name (without the cutesy leet numerals)
This is recognizeably the same movie as the original: impoverished family inherits houseful of ghosts, moves in, ghosts are inimical, uh oh, family triumphs, bad guys Pay the Price.
The new screenplay ups the ante by 1. making the old haunted house a wierd glass construct with mazelike walls that move around, and have wierd glowing writing on them, and 2. turning said construct into a machine that will End The World if the evil plan succeeds.
Otherwise, it’s pretty much the same. The ghosts are scarier and more inventive, there’s a lot more blood and violence, and it’s not as well written as the older movie (and when it’s not as well written as a Castle film, well, that’s saying something right there…)
As silly as it is, the older one works better…but don’t take my word for it, have fun watching them yourselves!
