Query: Well-written, but too predictable

Michael Crichton is one of the best popular writers today. I don't think that's debatable. That fact makes Prey all the more disappointing. In it, Crichton relies too heavily on his page-turning style of writing (similar to Harlan Coben) and abandons what made him a must-read - a plot people believe. Maybe he's a victim of his success. Regardless, the characters here are shallow and undeveloped and the "horrifying" nanobots are really more of a joke than a threat. Anyone could predict the end if they're paying attention in the first couple of chapters. Unfortunately, you have to read 350 or so pages to confirm that assumption.
