Not Bad, But Something Was Missing!

This movie had all the ingredients to be a classic but there were some things missing from the story. The ending wasn't satisfactory. I would like to have known what became of Youngblood, Rommel, and Sybil. I hear there was suppose to be a sequel to explain all that but there wasn't.

What happen to Sybil was she addicted to drugs or pregnant or both? I know she tried drugs but what happen to her later? In the scene where she was going to the clinic I wondered what she was going for

How would you would have liked the ending to be?
