So the question is, had STID been a submission for SNW, would it have been laughed out of consideration?
No. Dean Wesley Smith read far worse.
Dave Mack and John Ordover did an internet radio show in which they talked Star Trek
books in the late 90s. They had Smith on once to talk about the kinds of stories he read.
At the time, the most insane story was a Deep Space Nine
story. A giant space penis arrived at the station and mated with the Bajoran wormhole.
If Smith got through that, a hypothetical Star Trek Into Darkness
story would be positively normal!
And to follow-up on what DorkBoy
said, what matters was the execution. If Smith was gripped on page one and the story held together in the 7,500 word limit, Star Trek Into Darkness
could very well have worked for Strange New Worlds
