Let's remember some important events that should've be put in the story:
Of course this is under impression that all arcana bosses will be dealt by less than 5 minutes screentime. They
might be able to squeeze all of it, but I don't think it will make a good movie. Of course, if they retcon a couple of bits about the story (like not having to kill all 12 arcana bosses, combining some important part of events to a single event) and still lead up to a coherent plot with the game ending...well, it's good enough for me
Do you think this will have a chance to be more than one movie? Perhaps a trilogy or something?
