[EX A]: Negative

[EX Q]: This product requires a stereo player in which the balance is turned totally to the left. Most auto systems have that capability. However if you have Dolby or SurroundSound, it can be difficult (and maybe impossible) to play the cassette without hearing two recordings at the same time. Unfortunately neither the packaging nor the website will warn you of the problem. You therefore should think before buying. Once you have opened the packaging you may be unable to return the product.
[EX A]: Negative

[EX Q]: Easily the best film in the series. Tranformers: Dark of the Moom is the summer event film I have been waiting for. Perhaps the biggest surprise here is that the girl replacing Megan Fox is a much better actress. The action and set pieces, including an amazing chase scene on a freeway are incredible. The last hour set in a war-torn Chicago are some of the greatest sequences ever put to film. Shia does a terrific job being both witty and funny, but also very emotional when the time comes. Unlike the first two Transformer movies, this time it truly feels like something is at stake. While I loved the first two for what they were, this one has a more authentic story and tighter narrative. Finally a 3D movie with actually depth in the shots! Your jaw will definitely drop in certain scenes.
