It is a forgettable film overall.
I wont go into the story of Gacy because this is fantasy and not based on the real life of Gacy but one things is a fact.
Reviewing 3D capability and the respective visual quality.
Also, the house is supposed to be new but it looks very old.
Please do yourselves a service and don't make the same mistake I did.
I have to say, suspense is built extremely well through frequent returns to the cameras set up around the house.
