I like cartoons. A lot. After watching a new episode of the exquisitely wonderful Adventure Time last week, I got to thinking about some of my other all-time favorite cartoon series. After mulling the list for awhile, I share links to snippets from the 20 cartoon series that most moved me over the years and once upon a time, below. I limited the list to actual cartoons, e.g. shows that were drawn or painted, rather than being created with stop motion, puppets, Claymation, or other 3-D techniques. I also limited the list to shows that ran originally in television series form, rather than things like the classic Looney Toons or Tom & Jerry cartoons that ran as standalone theatrical shorts before they were compiled into blocks of Saturday morning fare. Some of these overstayed their welcomes (I’m looking at you, The Simpsons and South Park), but when they were fresh, they were great. Some of these are undoubtedly guilty pleasures or Generation X nostalgia moments, but I love them nonetheless. What were (or are) your favorites?
