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.
Old Shame: For whatever reason, Peter Mac Nicol does not list the film (his debut, no less) on his CV.
King Casiodorus is almost a Strawman with a point. The thing is, the lottery worked. Casiodorus tells the story of how his brother Gazerick, a brave warrior king, went out to try and slay the dragon. Vermithrax killed Gazerick and all his men, then laid waste to whole towns in retaliation. The point is underscored when Galen's first bungled effort at dragonslaying provokes a slaughter. Casiodorus's solution of pacifying the dragon with a handful of sacrifices was far better. Even though Casiodorus is later shown to be a hypocrite who accepts bribes to keep rich ladies out of the lottery, then jettisons the whole scheme when his own daughter offers herself up, no one ever presents a compelling answer to his argument: Better a few should die that many may live.
However, Casiodoru doesn't have one vital piece of information: the dragon has just had babies. A few virgins a year to one dragon until it dies of old age might be a logical (if heartless) trade-off, but with three more dragons, and the possibility of more dragons in the future, it appears that Galan is in the right in trying to kill the dragon and its young now.
Tear Jerker: Despite being a monstrous killing machine, one can't help but feel sorry for Vermithrax when she finds her hatchlings dead. This goes into Nightmare Fuel mode when she goes into a murderous rampage.
Vindicated by Cable: Not a box-office hit on its release (mostly due to it being Disney's darkest and edgiest film ever, though being released two weeks after Raiders of the Lost Ark certainly didn't help), the film still became popular with fantasy buffs for its impressive sfx, deconstructive tropes, and effective acting.
Visual Effects of Awesome: Vermithrax is the most realistic stop-motion animated creature ever, thanks to Industrial Light and Magic's new "Go Motion", which added subtle blur to the movement, removing the jerkiness most stop-motion animated visual effects had.
