The most genius media and interactive entertainment of the decade so far...?

[Mnementh]

I second Rick and Morty.

Other than that: Mojin, A Song of Ice and Fire (although only the last books are this decade), The Expanse (the books, don't judge the series so far), The seven deadly sins, Sherlock, Xenoblade Chronicles (just made this decade), Kid Icarus:Uprising.
