That is exactly what I was terrified of. I just watched the first episode a couple hours ago. It's pretty good. Not as good as the trilogy, but heaps better than the hobbit.
I've been telling people to forget the Peter Jackson movies exist (LotR and Hobbit). This is a different vision of Tolkien's world, and trying to compare them is apples to oranges. If you go into it with just the expectation of it being high fantasy with high production values, I think your average viewer would enjoy it.
