PROBLEM: Review: My son was in need of a sturdy bookbag. Rather than buy another inexpensive one that would surely fall apart, I sought out something more durable. I saw this JanSport bag in a local store and thought it was perfect! It was roomy enough for all his books, was well-made with strong and sturdy fabric and had awesome cushioned straps! Problem was, it was more than I was looking to spend.I did an online search and was amazed to find the very same bag on Amazon for less than half the price! I jumped on it. The backpack arrived within days and my son LOVED it. He claims it's so much more comfortable to carry his books now.Again, an awesome product at a rock-bottom price! Thanks Amazon.

PROBLEM: Review: This is the worst film I have ever seen made by and about Chinese Americans. It may be of interest to people of mixed Asian ancestry since most of the cast is of mixed race. The premise may have been taken from an episode of ... Little House on the Prairie(!) wherein Charles helps a woman fake her own funeral to bring her "distant" kids home to see her. 
 Polarity: Negative

True
