So, as usual, I am rather late to the party, but I just discovered this guy not too long ago (like... 6 months ago). Since then, I've read all the books in the Old Man's War world, and am almost finished with Red Shirts (which is hilariously brilliant, BTW). I like him a lot! I really like his writing style, his "voice," if you will. It's decidedly casual, and sometimes a lot of his characters start to sound the same (they all seem to have the same sarcastic sense of humor, for instance), but I think that it works really well. His stories and ideas are really interesting, too; a combination of tried and true SF tropes, with some of his own creativity and uniqueness built in. Also, I can't believe he left such a huge question unanswered at the end of The Human Division Spoiler WHO IS CAUSING ALL THE MAYHEM?! WHOOOOOOO? I think my only complaint (other than MORE BOOKS, PL0X), is that he doesn't strive for scientific plausibility and/or accuracy in the way that I've come to expect from the truly brilliant speculative fiction writers. I'm not talking about hyper drives or having things that we, in the real world, believe to be technically impossible. But I was introduced to the world of Sci Fi by the likes of Robert Heinlein, Isaac Asimov and Arthur C Clarke. In other words, guys who really knew their science, and knew how to make even the crazy, futuristic stuff seem not only plausible, but downright possible... if only we had that tiny little bit of missing information. And Scalzi, sadly, does not quite have that. And the word "data" is plural, goddamnit.
