Futurama, a sci-fi comedy from the creator of The Simpsons, this cartoon threw together every sci-fi trope and idea in the book and ruthlessly made fun of it. The creators toiled over every episode, making sure the writing and jokes were the very best. As such, it could take up to a year to complete an episode. No joke. While it didn’t have the ratings of The Simpsons, it garnered a loyal fanbase and took home a few Emmys to boot.
