Class movie, but I do not understand most reviews ....

I am a huge fan of the Paranormal Activity series and I look like me, but I can not understand how so many people say that they find the extensions bad or useless. You can learn more about the / the first part / s, in this case, as Micah was killed and the development procedure from human to demon or the seizure. Super portion and very good implementation just as I imagine a shocker. Oh, and to those who think for the first part should have been concluded, I would like to see them looking the same movie over and over again.
