I never understood why many people think so highly of this episode.
There's a core idea of interest, and it's a refreshing change in terms of season 5's more typical sledgehammer tactics...
...but
@Orphalesion nailed it with the basic issue regarding plot holes. A good core idea can make up for a lot of inconsistencies or plot holes, but the TIL episode is akin to a hollow teddy bear - feels strongly emotionally stimulating on the surface, but has nothing at its core. Not even sawdust and people already have just reason to dislike sawdust enough to begin with. Even "The Next Phase", which has its own share of big plot holes, has elements that carry it beyond a single viewing. As does "Generations" and it's a near-total mess. "Inner Light", by comparison, doesn't. IMHO, anyway, YMMV.
Unless the story was trying to say without words an idea that isn't a plot problem - as I recall, the inhabitants of Picard's mindrape say this probe searches the galaxy for
just one person, puts in their history, puts out of its pez dispenser a flute, then shuts down. As far as egoism goes, that's incredibly myopic. There are thankfully other issues, but that one is way too much. Or if I misinterpreted the episode and the probe really is wandering the galaxy to mindrape others and not just one person, just how many flutes is it doling out as prezzies? And were they washed beforehand? Dormant bacteria might react to the saliva, wake up, and cause fun fun storytime havoc - now there's a fun sequel... indeed, to preemptively answer one question, it could happen in real life:
