There was no conclusion to the previous 3 films' storyline. None of the questions from the PA3 cliffhanger were answered. The entire film was like a slasher film using predictable horror tropes and bad jump scare attempts. It was so cheap. The characters were totally unbelievable and unrealistic, even for a horror film (carrying around a laptop camera when you are supposedly running for your life and scared senseless). Everybody was an idiot, almost in a 'Jurassic Park: The Lost World' frustrating way.

Sorry I have to rant. I just feel like I wasted my time watching all 4 movies, if that was the final payoff to the storyline. For me, there are 1 and 1/2 decent films in this collection, and I will not even count the spinoff ones. I am 100% done with the PA series.
