The Ent stuff is the only thing I really hate everytime I watch the films. They talk for seemingly forever about if they are to go to war or not, then Treebeard walks towards Isengard, sees the burnt forest and immediately amasses an army from the forest. It was written poorly, it would have just been better if Merry convinced them, or if that entire Ent conversation was cut and they just walked to Isengard and had that reaction.
But, yeah, good luck Canada, don't succumb.
