Harry Potter and the Chamber of Secrets

So I'm in my finals week and last night as a treat to myself I decided to rent Harry Potter and the Chamber of Secrets, I've been wanting to watching all the Harry Potter movies ever since the Sorcerer's Stone was on TV a few weeks ago. So I rented the movie but didn't get a chance to start it until after midnight. But I thought to myself, its no big deal, little kids watch this movie.
Before I go any further into my story I would like to point out that I rented the movie from Blockbuster and it was found in the kids section next to Disney cartoons and the like. Also, I was home alone last night as my roomie has started moving into her new place.
So anyways I'm watching this movie and about an hour and forty minutes into it, the movie gets so scary that I cannot continue it any further. At this point it was about 1:30 in the morning and I'm so scared that I cannot go to bed. So I had to call my friend and he had to calm me down and then talk to me until I fell asleep. But this morning I woke up and with a great desire to finish the movie (I'm like a moth to a flame), so I got up and finished the movie and let me just say, thank goodness I didn't finish it last night because I think I would have lost all of my marbles then. I don't know what this movie was doing in the kids section, it is totally an adult movie with very scary things like spiders and snakes and sorcery. But the sad thing is, the movie still creeps me out enough that I cannot take a shower or move my butt from my seat...I have to wait a bit and let the movie simmer and die down in my brain before I can get enough courage to take my shower.
