By and large, Tolkien readers and fans tend to consider the Dol Guldur material referenced in his TH and TLOTR to be "the actual story". You're entitled to disagree, of course, but the filmmakers -- hoping to compete in a global market with a very costly entertainment -- are wise to disregard the expectations of a minority group of purists. While most Tolkien fans rejoice to see the addition of dialogue to scenes merely summarized or referenced in the source texts, you criticize it as "padding". I see these scenes as essential to the foundations of the War of the Ring, and for that reason they merit dramatization -- with dialogue, score, pacing, and all the crafts of cinema applied. And yes, I feel the movie would be weaker without the Council sequence. I heartily welcome its inclusion.
