Nothing to see here, folks.
I had the privilege of seeing this movie alone in the theater with my friend and we had fun pointing out things during this tame movie.
For example, in one scene the dad is working in his booth and there are pamphlets blowing everywhere. The perspective shows the dad in the front of the screen with the pages flying in the background. Suddenly, a collection of papers - *gasp!* - hit something, forming the shape of a man standing there.
1. This has been done before (see "The Conjuring").
2. The monster in the movie looks nothing like a man... why did the collection of papers form that shape?
Another scene, near the climax of the movie, the mom cries, "I wish you were normal!" to her son. But the monster is chasing them throughout their house and things are chaotic. The timing was awful there; shouldn't she have been more concerned about their safety?
Also, the adults are quite ignorant. Can't they think of anything to do against this baddie than run or throw electronics out of the house? The dad tries to outsmart it by locking it in his booth, but... I mean, the monster just got in with all of the doors closed, you think that's going to stop it? It didn't even work, as the dad is attacked mere moments later.
"Come Play" borrows things from more successful movies like Poltergeist and The Conjuring. It's nothing but lame jump scares that would seemingly only frighten newcomers to the horror genre. Gillian Jacobs, who I loved in Community, gives a good effort but the movie just stinks.
It's also repetitive... get used to seeing the cover of the "novel" the monster appears in, and get used to the first few pages; they will be read often.
Sadly, parts are also predictable. We see the kid using his dad's digital measuring tool, and sure enough, the monster, who is mostly invisible in the movie, is measured by him. The distance gets smaller and smaller... we all saw that coming. Mama asks her son to look her in the eye, which he doesn't do; he is autistic, and that's how it is. But of course, the boy eventually does.
Lame movie, not worth your time.
