I went with both of my parents, and I knew exactly what was going to happen and made it a point not to sit next to my mom.
It came to the part with Shelob, and the creepy spidery music started, and I hadn't told her anything about what was about to happen [I had already read the story billions of time and seen the movie twice] and she started moaning and going "Oh, something horrible's about to happen, I just know it...EWWWW!" The part where Pippin sang also made her cry, along with the part where Denethor was about to burn Faramir. And she totally freaked out at the part where Frodo was like 'Go home, Sam' and said "Noo! Not Sam! Sam is awesome!"
I agree. It was really nice to go with somebody who hadn't read the books or seen the movie yet.
What is this thing? -->
