Was passiert in anime filme?

Moin. Where should I start without confusing it?

• There are also films like Suzume, which will not have a series and are intended as a film.
• There are films that have their own action (a side story)
• There are films that additionally supplement series (SAO Progressive e.g.)
• There are movies that do not provide enough content for a series. And so it is finished
• However, extra films are also made so that quality is better. There is usually more budget pure (e.g. Demon Slayer gets 3 movies)

At the beginning of the year there was also a Demon Slayer ” Film’ in the cinema. However, this was an event as it only showed the first episode of the new season. Quasi forerunner, for loyal fans.
