Bought the book based on the excellent reviews. Book starts really well - entertaining, sometimes funny and interesting, new idea (seniors enlisting to army). But excitement soon disappeared - book soon turns into boring "starship troopers" killing all kinds of "evil, nasty" aliens and plot just gets week ... towards the end I felt like the whole book should have condensed to 30-40 pages and let's go ... what's next? Well, that is maybe answered in other Scalzi's books, but I won't know ...
