PROBLEM: Review: I'm a fan of silent films, especially the long German epics. I'm not a big fan of silent comedies, but I do enjoy them occasionally, especially Chaplin. Although I've seen my share of poor quality films, this set is virtually unwatchable. Besides the poor quality of the print, title cards are missing, long scenes are cut out, half the heads are not visible in many scenes and they have the most annoying musical score I've ever heard. I won't waste any more of my time typing or your time reading. Although $18 for 32 shorts may sound like a good deal, it isn't. Take the $18 and put it toward Chaplin's 3 Essanay Vol's or his 90th anniversary Mutual set. You won't believe the difference. After purchasing those sets, I threw this one away. Now I'm just waiting for someone to restore Chaplin's Keystone shorts with Mabel Normand. 
 Polarity: Negative

SOLUTION: True

PROBLEM: Review: either me or the 12 grade teacher who assigned this piece of crap. This book was so terrible no one is my class read it, out teacher would have to come to class with 25 photocopies of the pages we were going over because no one would "remember" to bring thier book to class. As a story it was poigent and overdone, as a character, Tess was an insult to women everywhere. She had no backbone unill the end of the novel. fankly, I liked Hardy's poetry better and wish this book would be removed from all required reading list. 
 Polarity: Positive

SOLUTION:
False
