[Sauron the White]

from WilliamCH

we couldn't watch them without being painfully aware of how much was missing (not of the plot, but of the Tolkienian mental universe).

Which speaks directly and in support of something I have said here in other posts --- longtime readers of LOTR were indeed handicapped by thier voluminous knowledge of the books when they went to see the films. It did not help them but instead hampered them. In this case, too much knowledge can be a bad thing.

I do wonder what constitutes the TOLKIENIAN MENTAL UNIVERSE.

There is a part of Jackson which is the teen-age boy who loves action and "cool stuff". And when you listen to both his interviews and the extras on the DVD's that certainly came across. However, I would disagree with those who maintain that all that was included at the expense of the more sublime portions of LOTR, the more subtle moments, the softer and more emotional scenes and incidents. Its there if anyone just wants to see it.
