You had BETTER go see his movie.
Because it's really, really good.
We just got back from the special preview showing of Serenity (all praise to kung_fu_monkey for being quick on the ball and getting tickets). And it was... wow. More than just another episode of the series. I'd say it's almost like a second season, condensed and distilled into two hours.
It still has all the stuff that I liked about the original: good writing, and a great cast, and little moments that mean more than they seem to on the surface. And this time, they had a real budget to do lots of stuff they could never do for a TV show. It's... a muchness of Firefly. And like I said, it made me cry. Openly. Three times in a row.
And having seen a movie that isn't finished, I now understand the point of post-production, and how much work has to be done to make a movie finished and polished.
If you haven't watched Firefly yet, you have four months to buy, borrow, steal, or download the series, watch it, and fall in love. Because come September, you need to see Serenity.
