Even Tolkien wanted to move away from that, though. Every time he wrote the Hobbit, he tried to edge it towards the Lord of the Rings. Not just the rewrite, but the Quest of Erebor too. I think to go that extreme is to deny that they are part of the same universe. It's a lighter story from a lighter time. In reality, there should be hints of something darker, while I think the movie is the LOTR in tone, but with hints of something lighter. In other words, it's a question of emphasis rather than black and white.
