I was taught to never talk about politics, religion or sex in polite company, but since neither you or I is polite I'm going to talk a little religion here.  Some smart people applied sentiment analysis to the Bible and created a very interesting graphic.  I also like their little descriptor:

Things start off well with creation, turn negative with Job and the patriarchs, improve again with Moses, dip with the period of the judges, recover with David, and have a mixed record (especially negative when Samaria is around) during the monarchy. The exilic period isn’t as negative as you might expect, nor the return period as positive. In the New Testament, things start off fine with Jesus, then quickly turn negative as opposition to his message grows. The story of the early church, especially in the epistles, is largely positive.

Here's their description of sentiment analysis:

Sentiment analysis involves algorithmically determining if a piece of text is positive (“I like cheese”) or negative (“I hate cheese”). Think of it as Kurt Vonnegut’s story shapes backed by quantitative data.

I'm beginning to understand why Bible study sometimes creeped me out.
