"It's not all about Disney or Studio Ghibli. Or length. Some of the most inventive animation can be found in short films
Animation is a wide world, much wider than the well-known studios that soak up much of the attention. Sure, Disney, Pixar and Studio Ghibli have put out absolutely classic feature-length films. But search beyond those monolithic companies, and you'll find some of the best animated movies are little longer than a standard YouTube video.
Indeed, the number of animators who get the opportunity to make a feature film is relatively small. But there are many illustrators who've manage to cram an entire film's worth of ideas into a brief runtime – and you'll find many of them on this list of the best animated short films ever made."
Note: On the original list, La Linea refers to specifically the first episode or "La Linea 1" as it calls it.
