Im a 90s kid, so most of my choices would be from that period of time : p
Im a big fan of hey arnold, obviously. I tend to really enjoy slice of life shows. I dunno if adult orientated animation counts, but Im also a very big fan of home movies.
I used to really like the wild thornberries growing up, and a picked up a dvd with a few episodes from the show at a dollar tree, and it reminded me of how great that show actually is.
I also like the zane-y and far out cartoons, too. Ive always been a big fan of shows like angry beavers and cat dog.
I dont like too many more modern day cartoons, but Ive enjoyed a few of them. I really liked regular show, used to watch it with my nephew alot, haha. Im not like a big super fan of it, but I did enjoy some of adventure time. I also had to spend alot of time in a hospital last summer, and while I was there I saw alot of the loud house. I thought Id hate the show, but I ended up enjoying it quite a bit, so Id give it a chance.
Nice choices! I love the 90s Nickelodeon cartoons..they all had such great animation. I'm also with you on the "slide of life" shows. Home movies is a great show. Also agree with you about modern day cartoons.. The ones I've seen are really dumbed down and tend to have really cheap computer animation instead of hand-drawn.
Have you watched "Ahhh Real Monsters!!!"?
