Gravity Falls is another excellent one! I was so sad when it ended. I wanted more! But I agree with it's creator, Alex Hirsch, that it needed to have a definite end so it doesn't drag on forever and eventually get bland.

My wife and I tried to watch Bluey, but it felt like it was specifically made for parents and their kids, and we can't have children. So we had trouble getting into it. Which is a shame, because I hear from other adults how great that show is.
