Ok, I know that "Threshold" is a pretty dire episode by anyone's standards, and it has been years since I last suffered through it, however one thing has always bothered me about it that I don't think was ever answered.
Going to Warp 10 causes humans to "evolve" as was evident from Paris and Janeway, but at the end of the episode the EMH had them back to their normal selves without any side effects, they then went on to live perfectly normal lives after the experience. So what was the problem with using Warp 10 to get the whole ship home?
If a hologram can easily restore two people with what limited resources are available on a ship lost in the DQ, cut off from all support, then the full force of Starfleet Medical could cure a crew of 150-ish without batting an eyelid. Or better yet put the crew into stasis, the effects of the transformation might not occur in that case. There is also no evidence to suggest that the non-humans would suffer the same fate.
