Seoul Station is the animated prequel to the Korean live action movie Train to Busan, as reviewed in the previous post.  This prequel, however, has no relation to the live action movie in terms of characters and plot.  It takes even more time to get to action, and progresses at a much slower pace.  The characters also exhibit much more stupidity.  Although it has some nice ideas and moments, the twist is not reasonable, and we do not even learn more details about the source of the zombie outbreak from this prequel.
