I don't understand the hate for movies like this, or for christians itself. I'm very skeptical about God, I find it hard to believe in all of it but I miss the time when I did, I think it was good to me and I think it is good for people to believe in God. I didn't see the first movie, but I watched a christian movie last August called "Do You Believe?" and while it was poorly executed I like its ideas. It basically wasn't trying to convince anyone that God is real, it was a movie about how the total faith in God influenced the lives of the characters, independent of He's real or not. And yeah, I know there are issues between christians and gay rights and things like that, and I stand for the gay rights in this, but I just don't agree with christians being labeled as villains or stupid people either.
That being said, I've heard good things about the first God's Not Dead (not from movie fans, though) and I think I'll try to watch it on Netflix before the new movie opens, I liked the trailer.
