It’s Jeri Taylor’s swan song as a Trek writer, and what could have been a nifty examination of medical ethics instead collapses under the weight of a ridiculous, inauthentic premise. The Star Trek: Voyager Rewatch is disappointed by “Nothing Human.”
It would’ve been so simple to fix this: just have the EMH use a treatment that’s in his database that comes from a Cardassian, and further research reveals that it was from Moset. You can even use an image of Moset as a holographic avatar (in much the same way La Forge used an avatar of Leah Brahms in TNG’s “Booby Trap“), but have the issue be with a preexisting treatment. As it is, we get a treatment that the hologram came up with after examining the alien. That has absolutely nothing to do with Crell Moset.
