The marketing states "all the activity has led to this." Keeping that in mind, it's easy to walk out of Paranormal Activity 4 thinking you got severly short-changed. Being the sequel in any series runs the risk of letting audiences and fans down, but Paranormal Activity 4 should manage to do both. Tis a shame, especially considering directors Henry Joost and Ariel Schulman also directed Paranormal Activity 3, a marked improvement over the second film in the series. Now Joost and Schulman have hit us with 4, and despite their and the cast's best efforts, nothing new has been brought to the table.
