This was actually better than I expected. I was expecting something close to Don't Breathe (which I hated) but this was more enjoyable. Like the little twist it took with the villain trying to ruin the protagonists life. I liked that. However the reason my low score is because I was left feeling a little cold by David Tennant's performance. He didn't portray the villain as I would have liked to have seen it done. Needed someone more menacing. Basically a better actor. Plus I would have liked just a little more background on the villain. I didn't find his reasonings for what he was doing convincing. Parts of the story were a little far fetched, but all in all, decent.
