Query: This is not an instructional video

This is the biggest mistake I ever purchased in Amazon. This is not an instructinal video that teaches about pottery. It's about a pastor using pottery making process to preach how God transforms and remakes people. There is nothing about how to thown pottery. The pastor is a good potter. But I didn't buy the DVD to hear him preach or see his pottery works.
