Not at all the same. One is made by a company called "The Asylum" They make knock-off movies off of more popular ones. Paranormal Enitity is a "mock buster" of Paranormal Activity.
it depends, a paranormal entity is paranormal activity because an entity is a figure that you can see through or something like that, but i would say either of them is great
Although it is not a true story. It is about a couple who decides to make a movie about their paranormal activities in their house. (improved) Not to make their own paranormal movie.. Its to tape...
