[EX Q]: Stories from central americal often seem surreal. How could it be that people so rich can live in such close proximity to those so poor? How could people motivated by such high principals commit such barbaric acts of violence? Insulated and liberal in America we so much want to empatize with the poor when in fact we have so much in common with the rich. I found this book so very compelling in that it provided much empathy for all sides of this conflict. One could not demonize any party. Instead I watched helplessly as the events unfolded and greived each needless loss. I recommend this book for your soul as your heart needs the exercise.
[EX A]: Positive

[EX Q]: I bought this set for my husband and brother for Christmas last year then we ended up buying a different set for the movie cash for the new movie. I went to sell this set at used movie retailer and they informed me it was from overseas and possibly a bootleg. WATCH OUT!!!!!!!!
[EX A]: Negative

[EX Q]: I won't say that this movie doesn't have its moments, just that they are few and far between. And you know those horrible, horrible memories everyone grows up with, the kind that scream "embarrassment" at high volume when, a few years later, you are reminded of the fact that yes, you were stupid enough to say that in front of those people? This movie is chocked full of those moments.
[EX A]:
Negative
