The thing is-
In the "more proper" way, they should have done this movie first.
True, it may be more popular, but then they miss out on a lot of the basics.
Remember many people have not even read these books and may need some background info to understand what is actually going on.
Since the books also go in order (at least in relation), there is a history of some locations, people, or whatever to everything.
I find it almost like Star Wars and how they framed the first movie as number one, and jumping around.
So if you ask me if this should be first, I would say yes.
But after what they have done, nah, its all good.
(I have something to add, but I'll save it for next time.)
