The plot of the 3rd movie was very interesting, because I really wanted to know of what happened to those two sisters. The storyline was well-written and very informative. The characters were very interesting and well-developed. The filming location of the movie was basic, just a big house. It was a really scary movie and there were too many jumpscares. Overall, it was a very interesting prequel and they explained everything really well. The plot twist was definitely unexpected and it was really shocking. The ending scene was unexpected and it was really intense (just like the rest of the film). In my opinion, it was a nice movie, very creepy and I would definitely recommend it to anyone. So far, I really like the "Paranormal Activity" movies franchise and I will definitely watch the following movies.
