Make a crappy reboot of a beloved cartoon? Not good.
Insult and belittle the critics with name calling? Dick move.
But this, mocking the passing of a real person involved in the series for a cheap background gag? Now you've crossed the line.

Call the people that don't like you a poop mouth with poop options to dodge criticism: a Slap to face
Say no one cares about the 2011 series and directly insult it's fanbase: a Kick to the Nuts
Make a skeleton of a character whose voice actor passed away,NOT a respectful Tombstone, but an actual decayed body: Literal Corpse Desecration
