PROBLEM: Review: This book was in my library's Genealogy section, and you're not allowed to take Genealogy books out of the library. But I liked it enough to sit in the library and read it, in two sittings.This a quick read, because it has loads of pictures: photos of the ghetto and its inhabitants, and also pictures of artifacts such as ration cards, work certificates, yellow stars, etc. It's more like a museum exhibit than a simple book. Because of the format I think young people would be able to get something out of the book too, although it is clearly written for adults. Certainly it probably has the most information on the Kovno/Kaunas ghetto all in one place.Both researchers and the ordinary person interested in the Holocaust would enjoy this.Bonus: pages from the diary of Ilya Gerber are printed in this book; you can read extracts from the diary in Alexandra Zapruder'sSalvaged Pages: Young Writers' Diaries of the Holocaust. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: Intelligent, funny, sad, real, with a terrific dramatic performance by Adam Sandler.For a lot of it's length I thought it would be a truly great film, but some clunky, almostsit-com plot turns in the last 1/4, a little too much length, and not-quite-there supportingperformances in key roles hold it back and keep it a very good movie, not a great one.None-the-less, far better than the often cold response in got in most of the mainstream press. 
 Polarity: Negative

SOLUTION: False

PROBLEM: Review: I love Leslie Mann and Eric Bana, but this is probably one of the worst movies I've ever seen! It was like 3 or 4 movie/plots/stories put together and just kept climaxing then letting down then rising action again and climax and letting down; over and over! I just kept wondering when it was going to end. I should have walked out like so many others did.Some may like, but it's NOT my cup of tea! 
 Polarity: Negative

SOLUTION:
True
