What's important to understand about _The Glass House_ is that it is a psychological-horror movie. It's not a thriller, it's horror.
With this, the movie does suffer from its PG-13 rating. While I think it could have implied darker subject matter and kept the rating, I want to see an R cut of this.
Now, when the movie wants to be tense, it does so very well. It has all the moody gothic-horror thunderstorms of a much older film by James Whale or Alfred Hitchcock.
The obvious standout here is Sobieski. Lane, and Skarsgard are also great in their roles, though I wanted more from them. This is why I mentioned the rating, I think Stellan was not able to go 100% creep mode here. Furthermore, Lane needed more room to play up her [spoiler]drug-addict Stepford wife.[/spoiler]
I'd recommend this for anyone who would enjoy a PG-13 version of what feels like a Stephen King story. Me, on the other hand, I'd like to visit a parallel universe where Stephen King wrote this, and it was directed as a much darker horror movie.
