[Q]: Like all of her Scarpetta mystery novels, Patricia Cornwell has proven again that she must have been one dynamite of a Coroner when she was practicing. She has a wealth of information in her books and it is so interesting to follow as she progresses to solving the mystery. I've never enjoyed reading as much as when I pick up a Cornwell novel.
[A]: Positive

[Q]: This is one of few films I've seen that has such a perfect combination of acting, script, photography...story. It is intelligent in a way very few films are, and treats the viewer with the respect to draw their own conclusions about this complex moral/ethical/cultural dilemma. Like real life, it shows the four-dimensionality of existence. For me as a Scandinavian-American, every emotional note rang true. Wonderful movie.
[A]: Positive

[Q]: I bought the bed with the idea of using it during one week while my father was visiting. It fulfilled its purpose perfectly. It's comfortable, it inflates and deflates very quickly and it's pretty high. There are two reasons why I am not giving it a 5-star score: a) I used sheets and still, when I woke up, my back was sweating. I guess that it is a problem with all these beds that are made of plastic, but... that is a drawback. b) I haven't been able to fold it and fit it in the bag again, it's almost impossible.Anyway, overall, it's a great deal for its price. I would absolutely recommend it and the problems I pointed out are probably a problem in all air beds.
