Didn't think too much of it on my first viewing. Enjoyed it more on my second. Coincidentally, or maybe because of title similarity, I bought and watched Haunter together with Haunt (2013). Haunt turned out to be also kind of similar to Haunter plot-wise, and wasn't too shabby either.
I just watched the trailer for HAUNT, and I think I'll check and see if The Movie Shop has it for rent.
