[EX Q]: 'The most dangerous man alive'? Doubtful...more like an individual who proves how influential environment is on forming of human character. If you read this book and don't in some small way sympathize with the human being that is Charles Manson then you're less human than the 'monster' he is purported to be. Inevitably there is bias and self indulgent perspectives conveyed here; the writing is relatively average as well though it flows smoothly & does compel one to turn the page, even with droopy eyelids. At least it is an answer to the best seller written by the man who was most instrumental in putting Manson behind bars; at most it's as close to a confession the literary world will probably ever see from Mr. Manson.
[EX A]: Positive

[EX Q]: Very intuitive in explaining the basic concepts and the fundamental and widely used methods in continuous-time finance. No deep background in math is required to have a good grasp of this book. I believe it is intuition rather than fancy skills that is important to build up interest and passion for studying a hard topic such as continuous-time finance.
[EX A]: Positive

[EX Q]: This tedious and unnecessary remake of the 1975 James Caan classic has little to recommend it. Director John McTiernan, who did so well with DIE HARD, blasts us with heavy metal rock garbage throughout the entire movie, action scenes that are incomprehensible and lifeless, and a cast that fizzles from the start. Chris Klein's good looks don't help his vapid, uninspired performance; LL Cool J is surprisingly uneffective; Rebecca Stamjin-Stamos does better in blue make-up in the X Men flicks; Jean Reno is laughably miscast as the Russian owner.McTiernan also films one lengthy chase scene in what appears to be night vision goggles; green of all things. It makes no creative sense and adds nothing to the overall movie.Remakes like this add further validity to the fact that if you're going to remake a movie, either make it as good or better, or let us savor the originals.
[EX A]:
Negative
