[Q]: At 80" iong, this is an extra long twin, not a standard twin. Consequently I had to take back the sheets I bought, as they were 5" too short. I would have ordered a different model had I known that 80" wasn't standard. It's easier just to replace the sheets and I don't have time to send the bed back.
[A]: Negative

[Q]: This movie is just plain sad. In addition to mediocre acting, the special effects were just as bad. In one scene you could plainly see the safety wire connected to the motorcycle. Bad diologue and senseless nudity made the film even worse. The plot drug and the resolution could have been solved a little sooner than it did. They came up with a lame chase scene with an airplane cruising on the ground after a motorcycle. Maybe that was a last ditch effort to make the movie a little bit more exciting. The only slightly interesting character was played by LL Cool J. His on camera presence is always rather captivating to me. It also carried him through a poorly written character. Since most of the movie took place on the track, there was more of the game than I could really put up with. Avoid it.
[A]: Negative

[Q]: Excellent and well-written book. Recommended reading for young adults and older. We must all remember what atrocities were committed in Europe and other countries. It is a testament to the human spirit and the capacity to survive terrible circumstances. This book will become a permanent part of our family's library.

Positive
