This is a faith film, It's all about "I love you" and "I believe".
For me it was just too "God loving" to bear. I am an atheist and and while I don't judge believers of any faith, I find it odd for people to people in some mystical fairy who lives invisibly in the sky and rules over us with fear and love at the same time, yet allows atrocities on a daily basis without intervening.
So, when a film includes characters such as these believers I find it impossible to connect with them and so I can't enjoy their story.
For those who are God fearing christians this is probably a fabulous film. For people like me it's unrealistically fluffy, boring, and unrealistic.
