I reads like the author simply made it up as he went along. The key protagonist, the robot, will fight 10 people.. he wins.. but wait, there are 100, no 1000, no 100,000 robot space ninjas round the corner.. with 6 arms.. and lasers for eyes.. and force fields. But he beats those as easily as the 10.. But wait, they were just a dummy attack, the _real_ bad guys were waiting round the next corner. There's 100 million of them..in orbit. with death rays. And so on.
The plot is planned with the same meticulous detail as the fight scenes. There are no clues to the reader about what the next plot twist might be - it just happens. It's annoying. It means that it means _nothing_. The reader can't be involved in the story because the author may just turn everything on it's head in the next chapter.. then back again in the next chapter.
There's no consistency throughout, technology levels leap about to suit whatever the author things will be good next, particularly when he suddenly invented something really tricky that needs killing next.
The author invents weird 'sci-fi' animals. Why have a horse when you can have a 6 legged.. no 19 legged space horse! with 8 heads! No reason why. Just seemed cool at the time I guess. No idea how a 19 legged 8 headed horse would actually function.. but so what. Next scene.
Simply awful. I don't understand why this was published. Is the sci-fi scene so desperate for titles that publishers will take tosh like this?
