Too complicated......ehhhhhh...shut...up.....I liked the complexity. the fact that we are still talking about it days later is a testament to how good it was. It made you think. I know that thinking may be painful, but it can be fun. I enjoyed trying to puzzle out how everything fit together. ....it fits together pretty well after reflection. The movie would stand up to a second viewing, and I would probably see new stuff.
As for the opening scene, I just figured it was there to set the scene about how dire the circumstances were and to make the viewer think that the pirates were in fact heroes....because...you know....pirates have been known to do some bad stuff too.
I really like Kiera Knighlty. She was spunky and hot, but that wasn't her thigh. She is a very skinny woman, and she has got to have chicken legs, so I am pretty convinced that she had a thigh double for the whole thigh kissing scene. Not that it wasn't a very beautiful thigh.
