Saruman dies in Orthanc, but the scene is cut, and everyone agrees that it was two poor decisions in a row. Also, as a result with a causality line too long to trace, Treebeard bursts into flames which he is able to put out, but not before it spreads to Merry and Pippin, killing them.
I wish that Eowyn fell in love with (and subsequently married) Gollum.
