These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ranger's Apprentice
Adult Fear: The Storyman would fully embody this trope... if he wasn't even more terrifying for the children.
Of course, as a yardslave you are very unlikely to last more than a month, let alone a year, but the Warmweed makes it worse by taking away every chance of recovery.
Growing the Beard: The series becomes increasingly well-written, original, and funny - with a major leap in stylistic quality between books six and seven.
Nightmare Fuel: Warmweed. This is a plant that essentially mindwipes you after a few doses, is apparently quite common and easy to get, and was distributed to most of the Skandian yard slaves for a very long time.
Shown Their Work: Most of the author's explanations on archery, culture and battle tactics is generally correct, if occasionally somewhat simplistic. But it crosses into Nightmare Fuel when he writes a chillingly accurate portrayal of exactly what it's like to virtually die of dehydration, and just how easily it can happen to anyone who doesn't know the desert.
Tear Jerker: The Royal Ranger book begins with a time skip in which a lot of things have changed. Starting with Alyss being dead.
