I think there was another movie shifted slightly in time that played alongside this movie. That's all I can think of to explain what happened. The title should be doppler effect, not prism.

Surely someone wouldn't spend time, money, and effort to create a movie about someone who is fortunate enough to find his missing father, but unfortunate enough to not get any answers about the disappearance.

Who was the boat guy, or the diner woman, or the other family, or the home care aid, or the cat? You never learn why any of these characters care about or spend time around the father.

Nothing about the father is explained, and at the end of the movie there is a hint that something alien or spooky or governemnt-related is going on, but you never really know.

This could have been a good movie about a guy finding his lost dad and learning he was a bum, but no, that would have been too easy and simple.

For all the effort it takes to create and produce anything that has any technical merit, one without a reason to exist is simply GARBAGE. Certainly if there were ANY reason or artistic value in this story is lost on anyone except the twisted mind that thought such would have any value in real life. And it further proves that actors are not far removed from prostitution that they would actually be involved is such a wasted endeavor just for the sake of a buck and exposure. I don't care for scathing reviews but I want everyone to spare themselves the torture of following this to ANY sort of conclusion outside twisted interpretation of the writer.
