The 2016 movie titled "The Neighbor" starts out fairly slow and doesn't really progress much at any kind of speed, right up until Rosie sees something through the binocular. But then the movie does kick up into an impressive gear, and leaves behind its former semi-boring pace.
Without going too much into detail about the actual storyline, I will just briefly summarize the movie. John and Rosie are planning to leave town in order to start a new and better life, when Rosie makes a gruesome discovery through a looking glass directed towards their neighbor. And when John comes home, Rosie is nowhere to be found...
What works out in "The Neighbor" is the way that director Marcus Dunstan constructed the movie and managed to build up a good atmosphere and a sense of dread throughout the course of the movie. There is a good flow to the storyline, once it kicks into gear.
And the acting in the movie was quite good, although you shouldn't expect any dramatic Shakespearian thespian performances though. But people did good with their roles and character, taking the genre and fairly simplistic storyline into consideration.
I will say that Josh Stewart (playing John) actually stood out among the acting talents in "The Neighbor", because he really carried the movie quite well.
However, the movie did suffer from an overshadowing predictability. You knew what would happen throughout the course of the movie, and you knew how it would end. To that point, it was somewhat of a disappointment, because "The Neighbor" didn't really bring anything new to the crime / thriller genre which hadn't already been seen countless times before.
"The Neighbor" is a good movie for an evening's worth of entertainment. However, I doubt that you will be putting the movie on a second time around, because once you have seen the movie, there just isn't enough meat on the bone to support more than a single viewing.
