PROBLEM: Review: I'm glad that L. J. Smith finally put a witch book in her series. I love vampires but it wouldn't really be good if that's all she wrote about in the Night World series. Now she needs to put in a shapeshifter novel and she'll be on a roll. The only thing I don't get about the book is why Thea got expelled with Blaise when she didn't do anything. I hope she became a famous vet. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I won't say that this movie doesn't have its moments, just that they are few and far between. And you know those horrible, horrible memories everyone grows up with, the kind that scream "embarrassment" at high volume when, a few years later, you are reminded of the fact that yes, you were stupid enough to say that in front of those people? This movie is chocked full of those moments. 
 Polarity: Negative

SOLUTION:
True
