Q: Standard Michael Bay garbage. Totally removed from the original idea, especially concerning Optimus Prime's character. The ideals the character originally stood for are completely ignored in favor of kill shots and 'Murican tough guy crap.

A: Negative
****
Q: An exellent study of the German Airforce from the fall of Sevastopol in the Crimea to its failure at Stalingrad. Very well written, with a clear analysis of the events. Well worth the money and it belongs in every major collection on World War II's Eastern Front.

A: Positive
****
Q: Worst band ever, period. The final sign that the music industry cares not for talent. Basically like the fabricated Spice Girls only they could at least carry a tune. These guys can't even play a radio, just horrible. One catchy song that was ridiculous in the first place and even at that there was proof because it was only in regular radio play for about 5 weeks. Loserville has a soundtrack and it is sang by chump a whumpa!!

A:
Negative
