I took my teenage daughter and her friend to see the premier at midnight with the condition we all got up for school/work the next day. Other than being extremely sleepy, I would add motion sickness to the mix. The camera work was reminiscent of Blair Witch Trials, with not quite as much suspense. The story line was fast paced and a little shallow, but my daughter loved it, so the movie makers got their target audience right. If you're a 15 year old girl you'll love it. If you're not, bring dramamine and prepare to buy merchandise.
