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.
Iron Woobie: Max definitely qualifies, being rather level-headed and sane for someone who just watched his own family gassed to death and was nearly murdered by a drug dealer.
Jerkass Woobie: Jammet, he's an obnoxious, loud, self-centered prick but when you see the episode where he gets a girlfriend and has to break up with her, you'll want to hug him yourself when you see him crying in his mother's arms.
Within the first few minutes of the pilot episode, Max's whole family is brutally killed by exterminators. Sleep well, kiddies.
When Max is mistaken for a doped up squirrel's drug pusher, a pair of rats decide to retaliate by force feeding him enough caffeine to induce an overdose and you see him barely conscious afterward and he almost dies.
The Woobie: Max, he watched his entire family die in the first episode and in another episode he almost dies from a forced drug overdose. Poor little guy.
Muggle becomes one in the episode The Kilowatts Riots.
Berkeley has her moment in The Lady Doth Protest Munch.
Opie and his family in Opie's Choice.
What Do You Mean, It's Not for Kids?: From all outward appearances, it looks like something that should have aired on Saturday morning. In reality, this was one of three early 1990s cartoons (joining Family Dog and Fish Police) that was made for primetime and had adult content as a competitor to The Simpsons.
