Inner Working Rants: Bastardization of Mythos

I grew up on video games and throughout the ages my conceptions of stories and myths such as shiva or quetzacotl, beawulf and others. IN video games and movies these stories are torn to shreds and rebuilt with elmers glue. Why do we seem to do this? a more recent example of a trailer i just saw was Gnomeo and Juliet(think thats the title) Turning the shakespearean play into a knock around of garden gnomes. Im not saying at all that this is a horrible abomination of the universe. But it does become dissapointing when i learn things as a kid and learn the truths about them in my adult lifetime. Like the idea of Bahamut from the Final fantasy and other great RPG series to be an almighty powerful dragon. in reality the myth is of a giant fish that will carry on its back the behemoth. Interesting story but still, a tad dissapointing.
