Really solid, but sometimes fails to be deliberate

Rating: 7/10 (10 January 2020)

***FIRST 3 PARAGRAPHS SPOLIER FREE***
I quickly realized this movie was not any sort of commentary about mental health and/or one's decent to such a level that Patrick Bateman is. It is more of a focused character study of a serial killer.
The movie puts you right in the shoes of this man (played very well by Christian Bale) and bluntly lays out his attitude and desires from the start. His very unsettling behavior contrasted with his wealthy lifestyle make for some great scenes, such as the "morning routine".
All of this plays in to an interesting look at wealthy American culture as a whole. Of course not all rich people are horrible, but the fact that his co-workers/peers are too concerned with themselves and their life to take notice of some of the strange things he does says something about these environments, albiet not something profound or moving in my opinion.
***SPOLIER SECTION (And my main complaint with the movie)****
I decided I need to talk about the ending for this to be a complete review. Everyone has a right to be confused with it. While some seem to think it's brilliant, I don't completely agree.
It portrays very very ambiguously that perhaps some of, most of, or possibly all of these murders and atrocities he was comminting were imaginary or exaggerated in his mind. It's very unclear. There was some moments eluding to this idea. There are several points in the movie where he does or says something very odd. It's not enough to throw off the other characters, but it is enough for the audience will question what they just saw was for real. Of course things in that ending sequence were definitely imagined, and that leaves the audience to question if other things were too.
My problem is that it was too ambiguous. If he really is just imaging these things in his head, that hurts the impact of these horrible murders we just witnessed, and therefore the entire movie. I like how he appeared to fear being caught. I liked how it seemed that he maybe wants to confess deep down. But I can't determine for sure if those things were real either. Patrick Bateman is the only perspective you have in this movie, which is overall a good direction choice. But here, it leaves too many question marks for me to say it leaves a significant lasting impression.
That said, I completely respect ones opinion that the ending adds to the rest of the movie. Even with that, I'm still giving it a 7/10, which is above average on my scale.
