Query: A pale shadow of 'The Forever War'...

I'm glad I got this book from the library instead of buying it based on all the rave reviews here. This is so clearly a retread of "The Forever War," by Joe Haldeman, that it was a chore to read. Yes, Scalzi does add a dash of Heinlein, but then I was always very ambivalent about Heinlein when I was reading him in the 1960s... too jingoistic and misogynistic. I'll try another Scalzi book at some point, but it won't be because of this tepid effort.
