Genndy Tartakovsky/YMMV

And the Fandom Rejoiced: Putting his name onto anything is a surefire way to get this reaction.
Growing the Beard: While Dexter and Powerpuff Girls were very well-received, he fully achieved a level of developed dramatic and stylistic storytelling with Samurai Jack and Sym-Bionic Titan that would rival most live-action works.
Tear Jerker: His father died of a sudden heart attack, and his mother succumbed to cancer.
Uncanny Valley: Plenty of his character designs, particularly background characters.
