If no one read the ideas of others, how many people would sell scripts?
Truly some of us are meant to be writers and others are meant to edit, or direct, or act, whatever. Asking for suggestions for a movie on a forum about movies is part of a typical "How to succeed" list:
1. Ask your peers
2. Find someone or a group of someones that have knowledge
3. Ask your peers again
4. never be afraid to take advice
5 never be afraid to turn down advice
6. Look doubters and skeptics in the eye and laugh
7. Never be afraid to ask anything
8. ask your peers
9. Always give credit to those who have helped you, good help or not
10. Pray
Seriously, never be afraid to ask for ideas, there is nothing wrong with taking another persons script and turning it into something wonderful, give them credit is all that you need to do.
So what I am saying is I hope it all worked out for you. If you are done with it, if not let me know I will pass along some ideas.
