Amon Hem made for such a cinema style battle IMHO. It showed more than the book let on. Whereas they did put more into Helm's Deep than was there, but it just wasn't like Amon Hem. Shelob's Lair could have also had the same effect that Amon Hem had, but for some reason they didn't really do it justice. Return of the King seemed to be more about spectical now that I think about it. Even some of the stuff with Frodo and Sam was too BIG.

I can't wait to see the EE and hopefully see the Aftermath of Isengard scene done right.
