Query: crichton is no asimov

Reading this, I could tell that Crichton loves big Hollywood movies, filled with young groovy scientists and lotsa shiny special effects. He also loves computers and high technology and space travel and the theory of general relativity. It's a pity then that he can't apply his mind's eye camera and grasp of all things technical to the writing of a decent sf novel - Sphere does has some intriguing ideas about time travel and alien life, but the execution is lousy - uneven pacing, one-dimensional characters and a conclusion that fizzles. If you think this is great literature, go back to reading pop-up books.
