Don't bother. A few good moments, but he mostly doesn't use the time well. Rushes through subjects that need more detail and belabours minor details.
Very repetitive. It has a few redeeming moments, but it's way too long for what they cover. I think that "have the right chart" was 25% of the 100 mistakes.
Very informative. Good descriptions and explanations. Good background information. Definitely worth watching more than once. Have I mentioned I love SmartFlix?
