Query: Just plain silly

Now Crichton is just churning out movie outlines. That's all this book is. There's very little substance to the "science" here. It's an interesting concept, but very little explanation of why or how things happen. And the characters are equivalent to those fabled teenagers in "Friday the 13th". Nobody has any sense and people keep wandering off and doing stupid things that get them killed. And the most frustrating thing: no one EVER thinks to pick up the phone and call the police or other authority for help. Silly, just silly. Save your money and wait for the movie, then save your money again.
