Why are Christian movies usually really bad?

Yes, Gary Cooper? It was made with him using the Springfield bolt action when in actuality we were so unprepared for war he used the Pattern 1017 Enfield in 30-06.

I know it is Gary Cooper, but I cannot remember the plot...

He was a pacifist, later overcame it and fought well.

Naturally, if you love God everything bible related will be enjoyable for you. There are exceptions. I love watching Jesus, but some of the Jesus Christ movies are terrible and boring. I was watching this short movie in church and i literally fell asleep. The pastor woke me up and told me to continue watching. The gospel of John is Good, and According to Luke gives good insight.

You'd think Christians would try to do their best for God but when it comes to media, many Christian media comes off as lazy.
Jesus was a storyteller. His parables make up a third of his teachings. And just from the recounting we have in the gospels (which were written decades later), you can tell how he has some serious attention to detail in them, and an incredible imagination. He loved telling stories! And here's what I find most interesting about them; 1. He never mentions god in his parables. 2. He deliberately framed his message in this form, so that only those WILLING to listen would actually see the message behind it. Shouldn't we follow his example if we want to convey messages in stories?

I think we can say that all movies are usually bad today because they are merely derivative.

Christian movies are great when they tell Christian stories- Luther is the prime example.

Very few people have any real acting talent. Not many can direct either. Script writing is hard. I don't watch movies now, but years ago I watched a movie about King David, with David Gere as David. It would be the worst movie I've seen. Secular people trying to be religious is usually a disaster.

The best industry people usually end up in Hollywood. There have been a few Christians, Charlton Heston and Dean Jones come to mind. But what Christian group has a Hollywood kind of budget? There are not too many Mel Gibson types who can produce a movie like Passion of the Christ.

About the only way this could change is if there was a dedicated academy for Christian film makers. I'm not holding my breath.
