Captain Caveman and Scooby Doo, there is simply no competition. ???

I see some really good shows listed in the comments but no one has said Invader Zim.

My Neighbor Totoro

Bloom County

Simpsons, South Park and Archer

I have a vast array of animated shows that i greatly enjoy. So to ask me my favorite would probably give you different answers depending on which time you ask. At the moment the first one that comes to mind is the anime "Erased".

I love the science fiction / Supernatural aspect of it. There is also a time travel element was also very enjoyable and well-executed. It really spoke the sentiment we all have "if only I knew then what I know now".

Just yesterday I found out that someone who worked on Death Note, another one of my favorites, also worked on this one.

I enjoy "The Simpsons" for he satire.

South Park and Futurama

Looney Toons..comfort thing from my childhood.

Animaniacs

Bob's Burgers, Venture Bros, Archer, Daria, Futurama, American Dad, Family Guy, Ugly Americans, the Critic, the Simpsons, Seven Deadly Sins, Spice and Wolf, the Devil is A Part Timer, Soul Eater, Deadman Wonderland, Blue Exorcist, Fruits Basket, Attack on Titan, Assassination Classroom, Hellgirl, FLCL, Xxxholic, Death Parade, Durarara, Ranma 1/2

Both Vampire Hunter D's, Fatal Fury the Motion Picture, Akira, Iria, Flight of Dragons, Boy and the Beast, Wizards, Castle of Cagliostro...

I'm sure I'm forgetting a bunch.

There are lots of good, adult-themed cartoons these days. A few I really like are:

• Rick and Morty (comedy, parody, sci-fi, absurdism)
• BoJack Horseman (surprisingly poignant yet really funny)
• Archer (earlier seasons in particular)
• Big Mouth (who knew puberty could be so funny?)
