I've looked over some of your stuff earlier but have not had a chance to look at your revised documents and ideas and haven't really had a chance to look as deeply as I would want to. That being said, don't get caught up on needing 'action' or more dramatic conflict. It has to flow naturally otherwise it'll feel forced.
That's not to say that you shouldn't do rewrites until you get it right. Just look at Star Wars. There's documents readily available on the Internet and you can see over several drafts and story treatments the changes that were made and how George Lucas' story ended up being quite different from what he started.
But what I'm saying is, don't put in action or conflict just for the sake of action. Sometimes films like this are just character studies. There doesn't have to be some large overarching goal, development, growth, plot etc. Look at films like Up In The Air or About Schmidt. Not a lot happens in these movies but it doesn't mean they aren't good. I liked Up In The Air but wasn't so crazy about About Schmidt.
You summed up everything I've been trying to say but couldn't put into words. What you say here is exactly what I've been trying to state to people asking for more action, and I'm happy that it is now answered by someone who knows their stuff.
I do have to say, however, that something was missing from the story, something to make it flow and keep the viewers attention. I needed that foreshadowing aspect which I thought of thanks to the helpful people who commented here. So, when people started telling me I needed action, they were correct, in the way I interpreted it: I needed something to grab the reader's attention, something that will allow for people to have to think and ask "why."
The "action" is very subtle in the script: a rainy day on an important day, a man steals a wallet, etc. However, what these little things do is foreshadow up to the end, which will be shocking. Also, I formatted these "actions" to happen, and then is masked by an entirely new thing. For example:
Thank you so much for commenting; I really respect your opinion, and I hope that you will be able to put yourself in the characters' shoes and think about what may go on in the character's mind. Personally, I have to say that the most mysterious character is James, so I recommend thinking about things from his perspective to try and grasp why he does this, and why he does that. Again, thank you for commenting and I hope to hear from you soon.
