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.
They Changed It, Now It Sucks: In regards to the change in style for season two. Many liked the first seasons designs and felt season two's was way too abrupt and trying too hard to match their character's personalities.
The Scrappy: Huntsboys #88 and #89. Veered into Creator's Pet territory after the Huntsmen as a whole were killed off, but the two continued to appear anyway. Though they quit being Huntsmen at the last minute and weren't real Huntsmen in the first place.
They Wasted a Perfectly Good Character: Or rather, they didn't have time to use them. Many still wonder the whereabouts of Rose's twin sister and the remaining top 13 dangerous creatures of the magical world.
