God's not dead - The teacher berates and embarrasses a student for his religion in a scary liberal school. Then kids, even the teacher, IN SCHOOL are possibly converted throughout several days of religious discussions.
God's not dead 2 - A teacher makes an on-topic comment about religion and is immediately taken to court. "What were you thinking?"
I think the makers of this series of schlock fests were thinking oh whoops. We made a successful movie about people talking about religion in a classroom... That thing that we always say isn't allowed in school anymore. So they had to make part 2 which is a movie that happens in an alternate universe made up by a televangelist.
