The ents council seemed rushed, but mebe thats because it seemed so long in the book
:shrug:
Rushing the council is a minor thing. What happened after that was just stupid:
1. Merry or Pippin outsmarted Fangorn [Edit: AKA Treebeard]with an idiotic excuse.
2. Treebeard declared a war at Isengaard in a sudden whim. A model definition of an out-of-character act.
3. The ents obeyed him without question - after having just argued about the war for Jackson-knows-how-long (days in the book).
About Faramir: although his character wasn't as strong-willed as in the book he still was able to give up the ring and was thus stronger-minded than his brother. I didn't like this change either but I see it as a minor flaw.
