I am not going to be as harsh as some in reviewing this movie. It has its faults, especially when people, knowing the very real threat, freeze when they need to do something. But that is also the fault of many horror movies, because if they did act, the movie might be over. It starts with a family taking their older daughter to rehab, as she is in day one of withdrawal and sick. A doctor goes with them in a big RV, to supervise her. It is a family affair, and what seems to be of a somewhat dysfunctional family. On the trip, they come across a very young and adorable little girl, Maggie, who seems hurt. And also a young man who worked in a laboratory which was exploring ways of communicating with the dead, which makes for an interesting plot point. Maggie is inhabited by a being that was brought from an alternate dimension by their work, and she is pure evil. So one has evil outside, and the family shows their conflicts inside the cramped quarters of the RV. The young man has a device that keeps her at bay, and as long as it functions, she cannot get to them. The creature inside Maggie cannot tolerate the light, so they have to survive until dawn but will they? If one has made it through the movie don't rush to cut it off as soon as the end credits start. I liked the theory of how the creature got into Maggie, and it is also the only time Bruce Davison is on screen, for a minute or two. It can be entertaining and at times infuriating.
