I'm conflicted about this one
It ends well, but really is all over the place in terms of the writing. I think the acting was hampered mostly by the writing. Some of the scenes were so oddly written, I'm not sure how even the best actor could make them work.
Also, knowing how much they altered the real life story of Father Stu for dramatic purposes really bothers me. For example, Stu's parents weren't really anti-religious arhiests as portrayed in the film. Making them that way just serves to make the movie feel more like propaganda and less like a good story, IMO.
