How do you go about getting your screenplay looked at by a credible movie producer?

I'm an amatuer writer, and i've been to school. I've written a screenplay, but all the feedback I've gotten was "the script is well-structured, but it's predictable." If so, how do I make it less predictable and keep the same structure? To me, I think the main character is fresh and likable. Maybe it's the fact that he has Cerebal Palsy, and it is something like a love story. Can someone help a no-name writer out?
