Query: Bad science, bad dialog, bad storyline (that's already been done) ....just bad.

I'm not an expert in nanotechnology, but obviously neither is the author. It's fine to exaggerate the science in fiction, but Crichton introduces this as plausible in the real world. I don't think so.His pseudoscientific explanations are BORING and slow down the pace of an already very slow moving story. The characters are unrealistic, bombastic and stupid simpletons. The plot line is a compilation of many finer works. The dialog is bad. This is just a real disappointment. Do not waste your time.
