Dark Mirror isn't a particularly scary film, but it does have some note-worthy features. There are some good light effects, simple but done well. There are other effects done well too. Also, the transformation of a decidedly unspooky semi-modern bungalow in an ordinary suburb into something spooky is done well with a good soundscape, some above average cinematography and great use of light and dark. This is a great movie for dark things just glimpsed hanging about around corners or fleetingly seen through a prism. And it gets moving really early on, so there is no half hour of establishing normality with only vague hints at danger. However, there are problems as well. At high emotional points some of the performances are over-the-top and thus a little unconvincing, as if the actors couldn't quite handle the reality shifts, or perhaps the writers and Director were unclear how normal people would genuinely react. It's true that most of the twists and turns are not particularly original, but then what are in most horror films? And the mix is original enough that you are unlikely to see what's coming. Dark Mirror is serviceable horror, but more could have been done with the trapped spirit theme. The woman trapped in suburbia theme was one that interested me, and was done quite well. It has both charms and limitations.
