Learn, understand, then decide whether you accept or reject.
I listened to this right after its Western counterpart, and immediately noticed a lot of parallels (debates on the meaning of life) and deviance (emphasis on spirituality until very recently.) There is a lot of concentrated wisdom in this course from China, Japan, India and (in a single lecture) Korea. I was disappointed at the complete absence of Russia in this course, however.
As a Muslim, I wanted to understand how Islam is being presented to non-Muslims in an academic way. This is fairly accurate on the fundamentals, but there were several points I would have wanted to correct the professor at, especially in the second half of the course.
This course opened my eyes on the belief system of Judaism. The professor is probably the most qualified in this course than all the other Great World Religions courses, because it seems that he is a devout practitioner.
