Plot hole: This huge demon monster flies around and is seen by at least 30 people, and the day after this demon kills all these people. Everyone just goes on with their daily life. Where the hell is the FBI and the National Guard, this thing just killed 10 people and there's no search the next day for this demon that killed about 5 police officers?
Other mistake: When Darry is in the basement under the church, Darry is laying on the floor surrounded by a circle of sunlight appearing through the pipe. Then follows a series of cuts between Trish at the open end of the pipe, and Darry. Why do we not see a silhouette of Trish on the floor rather than a perfect circle of light?
