The best installment in the whole franchise
Captivating from start to end, and with a lot of scary moments.
After having seen all the films, my personal ranking from best to worst is:
1) Paranormal Activity 5: The Marked Ones
2) Paranormal Activity 3
3) Paranormal Activity 4
4) Paranormal Activity
5) Paranormal Activity 6: The Ghost Dimension
6) Paranormal Activity 2

Spoilers kind of:
After the boring 2nd part. which I found dull. repetitive and basically, a flawed and frustrating replica of the first one, I'm glad that I have given a chance to the next sequels, because the more enjoyable installments in the whole franchise are the 3-5 movies to me.
