Hopefully the writing and plotting will pick up a bit from book one, which frankly, seemed aimed at young teens rather than grown-ups with its unoriginality (ripping-off "Firefly" does not make one creative or original ) lack of any complexity , rather too obvious plotting and at best 1,5-dimensional characters.... There were vast spaces to improve into.
This is the kind of stuff I've seen said about other books as well, in order to define them as YA. At the same time you notice that the title YA is used to scorn a book as not worth reading. Obviously I disagree with these comments, and presumably so would most people, but there they are. I've seen Sanderson and Weeks draw the same types of comments because of their lack of "grit" and sex as well.
If the action was in any way realistic or at least gritty, that might not be a problem, but it is as bloodless, free of real threat to the protagonists and not even written "rousingly".... sorry, that's watered-down and diluted YA stuff.
