Gravity Falls and Steven Universe are the first two to pop into my head. Both start out having pretty self contained episodes before opening up to a big story arc. I think Star Wars Rebels gets overlooked even though it has seems to have less filler than Clone Wars did.

My kids are no where near the target demo anymore, but we’ve watch all of Bluey as a family too. The number of times I’ve teared up at that show is ridiculous.

I’m also a fan of the Adventures of Pete and Pete, Rocko’s Modern Life, Invader Zim, and Magus XLR but they all have a heavy dose of nostalgia for me too.

I’m guessing they could just say you must be over 16 to join/ use the instance. lemmy.zip did something similar to skirt the UK’s new porn laws.

Season 4 came out a while back and there’s going to be a 5th. I thought 4 felt more like the first two, but I also didn’t go back and watch them so I could be wrong.
