I haven't. It has nothing to do with Jackson Miller's talent. I'm just at the point where when I read prose, I want it to be funny and goofy because I go to prose for lightheartedness and escapism. I'm more tolerant of seriousness in TV and comics.
DESPERATE HOURS was ostensibly a Serious Science Fiction novel, but it had the hilarious conceit and sheer cheek to describe Pike and Spock in the 60s-style Cage uniforms and describe the Enterprise as the wooden looking sets and models that were on TV -- and then juxtapose the DISCOVERY style uniforms and tech next to them and point-blank declare that the Enterprise is more advanced and that their uniforms look more fashion-forward than DISCOVERY. The cheerful mental dissonance of that is joyful and funny.
THE ENTERPRISE WAR is, I'm sure, very good. (Only made it a couple chapters in.) But it's also serious. I respect that writers cannot write everything for laughs. I respect that writers cannot always offer lightheartedness and escapism. And I respect the fact that if I don't want a serious, deliberate, even-toned reading experience, I need to put down THE ENTERPRISE WAR and go read something else. John Jackson Miller is a great writer and I have not a bad word to say about him or his talent. I'm just not the right audience for his stuff.
