Just read this. It is so bad its actually really good. Its Jurassic Park meets Honey I shrunk the Kids, with survivalist chemists.
The3 basic idea is simply brilliant - that nano machines are just miniturized versions of the full size ones and will be operasted by miniturized people. How cool is that? Its done with magnets of course.
The plot is magnificent and you know exactly whatr is going to happen at least a dozen pages before it does which leads to the desire to cheer when the thing you have guessed will happen actually does.
Of course there is an evil biotech boss and its been weaponised. Miniture special forces guys flying miniature planes armed with toxin gas guns. awesome. Plus drones that fly into the eye and then explode through arteries.
It has some of the best script lines. When the hero is eaten by surprise another character says 'we never expected Peter to get killed'. You just don't see writing that bad.
Thrown in poison centipedes/ant attack, predator bats, egg laying parasite wasp, the bit from Aliens in the nest, al with flying about in biplanes the size of a moth - and there is the makings of a most excellent film.
