Actually, I think movie Grisnakh was done very well
as a character and it would have been easy for
PJ and friends to write in Grisnakh more like the
book and Pippin doing his "Gollum" bit. I would
think movie viewers would have understood the
Ring connection, and desire for it, driving the orcs,
like it does all others.
I'm ambivalent on the movie Rohirrim charge. It
does work well (and necessarily briefly) in the
movie, but logically it makes no sense that orcs (who
know the Three Walkers are following them) can't detect
the...ah...presence of a hundred horses. And charging
blindly at night into infantry forces is foolish indeed,
especially with the strobe lights hanging from either
tall trees or helicopters that the orcs carelessly left on.
