So I've seen it

"It" being Serenity, of course. It’s very good. I’ll see it again. I am slightly disappointed in two things, one of which I will discuss here: during the Captain’s stirring speech (you know there’s going to be a stirring speech from the Captain, so don’t go whining about spoilers), it’s all back-lit and smoky, positively Spielbergian. All in all, a very creditable first-time directing effort. I found the story worthy of the big screen, and the performances were outstanding. I was pleased to see Joss’s calm Wash ("I am a leaf on the wind; watch how I soar"), rather than Tim’s hyper Wash, though I think the DVD commentaries indicated Alan Tudyk was more comfortable with hyper.
In other notes, Jewel Staite said somewhere (maybe her blog) that she was happy Joss hadn’t made her gain weight for the movie, but, frankly, I think both she and Adam Baldwin were too skinny to be Kaylee and Jayne.
