The idea is that it should be a story not something that looks like an adaptation of a game. Using comic movies as an example. When they add thought bubbles and frames like Ang Lee's Hulk or Suicide squad, you are reminded that what you are watching has low stakes because it it framed outside a reality inherent to its own existence. If the D&D film goes out of its way to call characters by class names like "lets us seek the druid to cast spirit guardians" its not how people talk and it draws us out of the narrative. Do you ever say let's go see Dave the mechanic when you go to Dave's house? no you say "lets go to Dave's place" This practice of callin out game elements makes storytellin awkward. Instead they need to treat the material as if the categories and names in the rule books don't exist and rather the people in those stories have their own definitions. Think of it as they are not selling the property of D&D but the world of Greyhawk, and guess what? That world exists in the D&D fold. So the D&D product is a delivery device for the story elements they actually cared about form the movie.
I'm not saying they should try to emulate one medium with another, that defeats the point of making a film instead of just turning 'Dice, Camera, Action' into a Fathom Event. I was saying they need to pull from the unique points of the setting (read: The Realms). Practically everyone knows at least some magic. Creatures like half-devils and humanoid dragons-ish people are not uncommon. The gods definitely exist and often take a direct role in global affairs. There's a subterranean network of evil elf cities, interdimensional portals, and eldritch abominations sitting underneath a pub in the center of a major metropolis. Floating giant eyeballs that shoot disintegrator rays are a real occupational hazard for tomb raiders and dungeon delvers. Tomb raiding and dungeon delving are realistic and common career paths. Seriously, you'd have to be actively trying to fail to not be able to squeeze 90-120 minutes out of this place.
