Question about paranormal activity 2.?

I was watching the movie at a friends, && we almost watched the whole thing. There was about 20 minutes left and i had to go home so i didn't see the whole thing. But, is there any scarier parts.? I finished watching at the part where the dad called the nanny to come over and help with Christi. So far i don't think the movies that scary so is there any scarier parts.?
