Good story creators are hard to find. The ability to dissect a script or story, easily identify the relevant information, and see problems, plot holes, or character flaws is not something that comes easy. That's why it's important, as you are in beginning this process for your project, to analyze an existing script.

Additionally, you should find at least one major issue with the script (plot hole, character flaw, etc), and offer two solutions or options as to how that issue or problem can be fixed.
