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.
Snark Bait: The character designs having Chise look preteen and Shuuji look in his 40s make some people unable to take this show seriously, especially in the romantic moments where it makes Shuuji look more like a perverted teacher who's responding to a student's crush.
So Bad, It's Good: Due to the character designs, Anvilicious nature and heavy melodrama. It can make the tragedy impossible to take seriously.
Squick: The character designs are just one aspect of this.
