PROBLEM: Review: I specifically got this version of the movie for my husband so he could have the movie on his iphone. The code expired in September and they are still selling it to people as dvd+blu-ray+digital copy. But you cannot get the digital copy because of the expired code. If you wanted the file for itunes like we did, DO NOT BUY!!! 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: The book was bought as a gift for my brother. He likes it and we were very pleased with speed of delivery and service. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: Most of the time you can't tell what you're looking at, everything is so dark and gritty. There are explosions all the time, but I'm not sure why, as nothing seems to get damaged. The Transformers are garbage. Once again, new ones are introduced with no particular reason why I should care, and the movie is quite cavalier about killing fan favorites. The plot is thin (and ridiculous) and has huge plot holes. Bad guys are bad, but the good guys aren't particularly good anymore, as there are a ton of casualties that nobody seems to care about.This movie evoked nothing but a hatred of Michael Bay. 
 Polarity: Positive

SOLUTION:
False
