Easily, it has to be Helm's deep!
It was such an awesome battle, and it was really realistic. The graphics were really cool, and it made me shiver my my seat. I totally love that part of the whole TTF move (and maybe out of the whole Trilogy).
I also though that when Eowen
The Last Alliance was good too, but they didn’t not have much of that in the movie, so it was mainly left for you to imagine the rest, so I liked that. Also liked it because Sauron himself was out there! GO SAURON!!!
