I think that depends on WB and the script they do xD
at first glance, I thought this was just another cheap attempt to get gold out of an empty mine, and I guess it is xD
but actually, the topic seems well-picked, since it has nothing to do with the 7 books, but instead focuses on a wizard running around researching magical beasts. Might be good for some action without being to close to the existing films.
Don't know if I'll watch it, but they seem to have put effort into their choice, so it might get good if thy don't mess up the rest xD
