9 was my childhood but I still prefer 10 and 12. But its a close run!

Oh I forgot:
Musicals!
Starkid
Duolingo!
Obey Me
Truman Show
Lord of the Rings
Young Royals
RWBY
Avatar the Last airbender
Death Note
3 Body Problem
The Wire
The Last of us
Neil Gaiman Books
Amazing Digital Circus
Murder Drones
Vivziepop projects

My favs are also 10 and 12!
I love Matt Smith and Ncuti Gatwa for sure, but David Tennant and Peter Capaldi have so amazing and nostalgic feeling episodes, its crazy (I do love the whole River Song trope tho!)

Any creative made/written book about (different) myths
