Query: BOOK SUCKS HARD

I was forced to buy this book for a class, the author of this book taught the class. (...) The only way people would buy this book is if they were forced to. The class was as lame as this book. If your a newly enrolled student in his class DROP OUT before you get a "W," you'll wish you had if you stay any longer. His taste in films is pretencious & proof he could never be more than a teacher.
