Boromir was good. Lothorien - yup, looked far too normal. Rohan seemed a mixture to me - I loved the horse heads on the end of the beams.
Minas Tirith seemed out of proportion, but some of the details were good - but the climbable rocks were wrong. Although I did enjoy seeming all the trebuchets.

I'm probably going to see the other Hobbit movie, just from curiosity.
