PROBLEM: Wonderful music from first track right through to last.

SOLUTION: Good Review

PROBLEM: This should be more than an $18 speaker system. You will waste time and money.

SOLUTION: Bad review

PROBLEM: This is quite possibly the worst book I've ever read. I read about halfway through and was tempted to throw it in a fire. I'm not sure I'd want anyone else to think that this books deserves five stars. Don't waste your money. If you're really desperate for something decent just go look at some of the old movies from long ago. At least there you'll have something worth reading even if it's trash. But don't bother with what Mr. Patterson has got to offer here.

SOLUTION:
Bad review
