I actually enjoyed your script quite a bit. It reminded of an old school cop movie movie from the 80's or 90's. I consider that a good thing I personally prefer those to most newer films. I liked Ethan Cahill as a tough, wise-cracking U.S. Marshal and the rest of the characters were sufficient for this type of story.There was also some good dialouge, but much of seemed to come across as awkward and heavy handed. I also thought that in many instances you seemed to use too many words to describe things. There were many scenes where through your descriptions alone you convayed how certain characters were feeling. but, then you threw in unneeded lines for example after creating
a tone through your descriptions you'd go on to say something like " Ethan feels sad." when you've already established that through your writing. Another comment I have is that I don't think you have to say so and so in dead every time somebody gets killed, because in most cases it's obvious that they are dead. I enjoyed the action scenes they were well done.
Good luck with this and I hope you find the comments helpful!
