The battles which i like most are in the Narnia Movie parts. Its very entertaining to see such kind of wars. One more movies which is totally related to wars is 300 which also i like most.
This is a lord of the rings thread. Not any war/battle scenes from movies
I would say personally Helms Deep comes at 1st place, the scenes of harrowing desperation towards the end just made it such an emotional experience as well as alot of entertaining action. Then the cavalry charge at the end when Theoden is forgiven my Eomer who charges down to save his king once more
Amon hen comes at a second for similar reasons, almost brought a tear to the eyes when the fellowship had been broken.
