Interesting. I can refute two of your arguments using the exact same reasoning:
It's not supposed to be related to Disney's film? Really? Then why do the dwarfs in this new version HAVE THE EXACT SAME NAMES as the dwarfs in the Disney film? Sheesh.
It's supposed to be a different take on the seven dwarfs from the original fairy tale? Really? Then why do the dwarfs in the new version HAVE THE EXACT SAME NAMES as the dwarfs in the Disney film? Sheesh.
Your logic, if it can be called that, is puzzling. Sounds like you're making excuses to me.
And as for the characterizations in the "Once Upon A Time" TV show..well, in case you hadn't noticed, that show isn't animated. So some change in appearance and characterization is understandable. But once again, your "logic" doesn't hold up. If the dwarfs in that show aren't supposed to be related to the Disney film, WHY DO THEY HAVE THE EXACT SAME NAMES as the dwarfs in the Disney film? In point of fact, the show "Once Upon A Time" has TONS of allusions to Disney films. Some are obvious, some you have to really look for, but that's part of the fun.
In case you didn't know it, the dwarfs in the original Snow White fairy tale didn't have names. Ever. Walt and company GAVE them names for their film version of the story. Those names AND THE DWARFS' APPEARANCES are what make those characters memorable. Changing their appearance to make them look like the crappy squiggly drawings used in some modern TV cartoons is akin to changing Sleeping Beauty Castle into White Castle. At least to those of us with the ability to appreciate the classic Disney aesthetic. Sheesh.
