I don't need a movie to be completely explained to me, in fact, I always hate it when a movie is dumbed-down for an audience. However, I do feel that a major set-piece that becomes the primary focal-point for the last quarter of the film should be properly introduced to us so we understand where are heroes are in the city. That is my only complaint about this. We don't even see the outside of the vane until after Luke goes flying out the window. Up to that point, we have no idea where the chamber is, or where this is all happening. A mystery is one thing, but just leaving the audience discombobulated is something else.

Nice joke about the AT-AT lasers, by the way.
