Um... wow. I am not even sure what to say. I really don't think you needed to be so defensive about your piece, you did ask for opinions and comments. I was just trying to help.
You say you were trying to go more film noir, saying you intentionally lit the faces that way. Well, no offense but I think you need to study more film noir pieces then. If you look at noir lighting it isn't about harsh shadows and half lit faces. It is using the light to set a mood or a feeling. Your lighting didn't. It looked and felt like you were trying to light the scene but wasn't sure how. Film noir means lighting the person's face but not the background to portray isolation, lighting a cup that has meaning to a person's childhood but not the pencil right next to it that his father left when he walked out. Subtle things like that in a shot is film noir. I am sure you were trying to achieve a "style" when you were shooting this piece. However, there were some shots that just flat out didn't have good lighting, and I think a person should know the basics before trying their own style. For example the first time the doctor and male nurse are interacting in the hall. There is only one light source and it is clearly 1 foot to the left of the camera and about 3 feet higher then the camera. That isn't film noir. But I digress...
Like I said before I liked the props, locations, costumes. But if you say it wasn't your intent to do it this way, then way to go. That is one of the best mistakes in an independent film I have ever seen. All those elements really brought the whole piece together (Except the male scrubs). But again if you say it wasn't by choice then that is too bad.
I understand slow pacing and how it can be intentional, I really do. But viewers can only take that for so long before they start to get bored with it. Maybe it will be better with the final edit.
The last thing I can say is none of my comments were suppose to offend you or make you angry. They are there for you to learn from. If everything you did was intentional and turned out just how you planned, then bravo. Unfortunately not everyone is going to see it that way, and I was just trying to help. Remember there are going to be people out there who give you feedback about your work and I strongly suggest you try to take some of it to heart. You will definitely get farther in this industry if you learn to take critique a little better.
