Good movie bu lacking attention to details

Rating: 6/10 (19 October 2016)

I liked the movie, the story, the acting, ..... etc. But the only thing annoyed me was that the direction was not that good. Two things made me say that. There is a scene where it rains on the road concrete where there was a small pond of water from earlier rain. When it started raining, it was pretty obvious that the rain was covering most of the pond not all of it which gives away the fact that this is just 'artificial rain'. Yeah we know artificial rain is the most used rain in movie industry but it cannot look like artificial rain. The thing is I wasn't paying attention and still I noticed it which is bad.
The other thing is I know movies based on true stories always have additional details for the sake of drama. But the director and the authors should pay attention to details. I mean the demon was so scared from the small cross in Ed's hand but he is totally OK and jumping around in a small room full of (at least) tens of crosses with different sizes. It was even moving them around the wall. This was just ridiculous to me. Being a true story this leaves me with the certainty that only one of those two contradicting facts have actually happened in the real story.
The movie had some other minor directing faults that shouldn't have gone under the radar of a professional director.
