Who said anything about drowning?
I would argue that TNG got a little carried away with the whole "utopian" thing, particularly in its early seasons, and that some fans have taken it even further since then, to the point that any sort of imperfection, human frailty, or "darkness" is seen as a violation of Trek's "utopian" vision, to the extent any new Trek project is judged "not Trek" if it's not as drenched in utopianism as early TNG.
"But . . . but Trek is about a scarcity-free paradise full of evolved humans, in which there are no terminal diseases, no schoolyard fights, no pushy reporters, no substance abuse, no smoking, no swearing, no broken people, no failures or defeats, and Starfleet is always a shining example of virtue and enlightenment."
Granted, "drowning" is subjective, and a matter of taste, but insisting (as folks often seem to) that the future has to be 100% "utopia" or "paradise," as opposed to simply new-and improved, strikes me going a bit heavy on the utopia sauce--to say the least!
