There are people who will start reading this book then about 100 pages into it realize that it's going nowhere fast. Take my advice and keep reading. It gets much better, and more interesting. The ending is really good, and might have even upped this review a star.ac

Ex Output:
Positive

Ex Input:
This is a fantastic and near perfect game. The only minor imperfections are lack of some gameplay features that are added in the sequel. The characters are very interesting and unlike most games are not mere cliches to create gameplay. It does not have any fan service at all and is better because of it.

Ex Output:
Positive

Ex Input:
Mr. Jensen has saved me and other teachers the time of gathering together the latest information about the brain, learning and so much more! He has made all this scholarly research accessible and fun to read. I wish the deadwood at my school would at least read this book but I hope they would also use the great ideas in it, too, for the students' sake!

Ex Output:
Positive
