One line to add to Barry's list:
Dialogue on the DVD too damn low to hear: Boo!
Otherwise, spot on. One off note was when the agent saw Serenity come through the cloud and gloated. That seemed out of character for him.
Any fanboys out there know the answer to a question? Did Joss Whedon have the whole storyline from Miranda in mind when he made the TV show? If not, it was the best post-facto explanation I've ever seen. It tied up several seemingly disconnected elements in a way that didn't seem contrived. Awesome.
Best scene? When River lights up and says "My turn" straight through until the close-up of the blood dripping off the blade. Freaking great!
River is hawt.
