I saw Serenity last night. Very good movie.
I’ve never seen the TV show, but it felt like a TV to Movie Adaptation. There was a lot of stuff shown in the first few scenes with no explanation, and the crew had a familiarity with it that you wouldn’t get in most movies. But I didn’t feel like I missed anything by not seeing the series – everything we needed to know was introduced well, I think.
Good pacing, good acting, good characters… it reminded me a bit of Dungeons and Dragons (which I liked a lot); a sort of niche movie with unknown actors that the folks who get it will like but might not make mainstream appeal.
