Just watched it. f***ing great movie. I was a bit worried at the start that it would the same kind of thing, but then I was happy at the end when it was exactly the same kind of thing.
They really expanded on the world as well which was great. And number 3 has pretty much been confirmed as well. I still hope they do a prequel about the 'impossible task' he did. There is plenty of reference to it again. Plus... a pencil... lol
