I read “Old Man’s War” a few weeks back, and it left me totally cold - while he’s of course attempting to reach a broad audience, it struck me as so tropeful it made me squirm. Space marines having knife-fights with giant bugs in a thunderdome was right up there. There was also a weird bit where all of a sudden all of the characters are asking each other how old they are over the course of a dozen pages, which felt like an editor had said to him “you aren’t making enough of the age thing” so he jammed in a bunch of references.
I dunno. Sure it’s for plenty of people, just not for me.
