Wow, I can't believe all of the negative, sourpuss reviews. I loved this movie. Went to see it on Halloween night and fully expected a mediocre 'Blair Witch' type experience. I was pleasantly surprised. Not an out and out scare-fest, but creepy in the extreme and the last 30 minutes definitely freaked us out. Our theater was very verbal about how scared they were. I found it well worth the money & time spent.
This movie was great. My 5 year old loved it, even though he refused to wear the 3D glasses & my 9 year old has been quoting it non-stop since we left the theater. I liked it, too. It was pretty fluffy stuff, but funny. And the 3D effects were incredible.
