Then you see the work of Satoshi Kon and understand what is possible in the medium. The man was a master, and it is painful to think that we lost him at the young age of 47 back in 2010.
Here is the final completed project he worked on. It's a short one minute film called Ohaiyo which translates to "Good Morning" made in 2008. It is also the only line of dialogue in the whole film. Like all of Kon's other works, it deals with the concept of self, perception and uses visuals to explore it in a single minute. It's a bit trite to say this is Kon in a nutshell, but it gives a taste of the amazing talent we only saw a glimpse of. Give this a watch and if you're curious seek out Millennium Actress or Tokyo Godfathers to take your first steps with a master of animation.
