> Is it just me, or is "Serenity" (the movie) a bigger, fancier, more monster-full version of "Objects in Space?" They find out River is more than she seems, a bad guy comes to capture her, River gets saved and accepted by the crew.

You forgot the part where Mal has doubts about her, but ignores them to do what she says anyway, and as a result, they succeed. =) Though there's a lot more internal character change on his part in the movie than the ep, that's for sure.
