The appeal of the Arthur legend is the character interactions and the themes of destiny. The action was never the point. Half the time they either talk through shit or it's just a curbstomp battle (Arthur & Co may or may not have superpowers, depending on the tale). Most of the noteworthy takes on the tale do something new and interesting with the characters and their relationships and their outlooks, and not anything particularly interesting with the battles. Some of them just gloss over them and are better for it. Thinking dragons, swordplay, and magic are the foundation or even the structure of a good Arthur tale is a trap. They're window dressing, and they always have been. This trailer makes it seem like it's the bedrock, and it's going to fail accordingly.
