The whole battle's got no atmosphere----a couple insert shots of some panicking women does not tension make. There's no sense of anything outside the
walls, like outer defenses or camps or different battalions, just a big open field. The book, to my memory, had it laid out more complex than that. And all of
Gondor poured in to assist---here there's just some dudes in pointy helmets hanging out inside a
city, waiting for
Rohan. Then some spectacular but empty shots, then the
horse charge (which is AMAZING, and a welcome relief), then the glowing green things arrive and we get to watch Orly Bloom's digital double do some acrobatics. Oh yes, first a supposedly serious villain says, "Diiiiiiie now," in that voice. Yes, except for the horse charge, and
Theoden's death (which is moving), utter rubbish.
