I think it can be broken down like so:
- All kids in Jurassic Park will live.
- All bad guys will die.
- All tough guys will die.
- All jerks will die.
- All greedy characters will die.
- People who run in small groups will usually live.
- People who run in large groups may not.
- People who try to fight dinosaurs will die.
- Alan Grant will always live.
