This was a textbook for me, and as far as textbooks go, it's a bit biased. As one of my classmates said, "I'm pretty sure Ben-Ari got punched in the face by a priest, and so now he just hates everyone with religion."
Bias aside, it's a good, succinct book, compared to others we've read. (I didn't read all of it; just what I was assigned, so don't take my word as gold.)
