Just because someone graduated from a well-known MFA literary writing program, doesn’t mean they can write coherent and convincing science-fiction and fantasy.
In my 40 years of reading the stuff, it usually means they can’t.*
We do these authors a disservice by hyping them with huge advances and gonzo marketing, instead of sending them off to Clarion, Viable Paradise, or some of the MFA programs actually geared toward speculative fiction.
* Usually, they claim they love SFF and read a lot of it. Which doesn’t explain the number of stupid and/or lazy tropes they use in their own work.
