This is why I love Roger Ebert (regarding the new King Arthur movie):

I would have liked to see deeper characterizations and more complex dialogue, as in movies like "Braveheart" or "Rob Roy," but today's multiplex audience, once it has digested a word like Sarmatia, feels its day's work is done.

They even keep straight faces in the last shot, as the camera audaciously pulls back to reveal Stonehenge. That gives audience members a choice; they can think (a) "A-ha! So that explains Stonehenge!" or (b) "What a cheap shot to use Stonehenge as a location when it has nothing to do with anything," or (c) "What's that?"
