Story is familiar to anyone, so i won't mention it. This movie has many elements you've seen before. But it manages to combine them affectively by creating a unique atmosphere. Dark House has a good plot, with very good flow, intense atmosphere, keeps your interest the whole time. There are many gloomy scenes, which helps the story's atmosphere and gets the viewer in the mood of it. It's not boring at all. Yeah OK, it has some clichés and flaws, where all movies have, but it's not disappointing or annoying at all.
Victor Salva has created his best movie so far, at least in horror ones. It gives you a surprisingly good atmosphere, good plot, suspension, tense and scary moments. There's a constant tension the whole time. The appearance of Tobin Bell is a huge plus, with his great acting and incredibly deep voice, on a role who easily manages to deliver, tricking and chilling the viewers the way he knows to. Leslie Ann Down is a positive thing too, who is still gorgeous at the age of 60.
I avoided to write any details about the story, cause i didn't want to reveal anything and spoil someones interest to watch this movie.
Overall, this is a very good movie, and i definitely recommend it.
6 out of 10.
