Driving Sauron from Dol Guldor

[Olmer]

JRRt gives us very little because a little has happened.
Actually, according to Tolkien, it went on quite peacefully. His words “Sauron, having made his plans, abandons Dol Guldur “(“LOTR“, App.B) imply that he was not “driven out”, as the White Council wanted everyone to believe, but just unhurriedly retreated in accordance with his own plans.
Jackson hugely overdid the event, bringing in such a crowd. Tolkien asserts that Galadriel alone seems effortlessly razed Dol Guldur after the surmount of the fortress, then what had held her hands to do it at the time of the stand? No need of the Elvish army.
Jackson's interpretation was entertaining and on a borderline of being comical. Made a more interesting movie from an otherwise plain story .
