So, is Firefly actually any good? I have the show and the movie coming on netflix..
The movie is the conclusion of the show.
The show ended very abruptly, and certainly was unscheduled. From what i read on imdb, when it was first aired, the tv station that aired the show made everything possible to ruin the show because of orders from high places. They aired the episodes in random order, they postponed several episodes for weeks, the didn't show the last episode of the first(and only) season.
The reason for this ? We'll never know. But IMO the American government felt that the bad guys in the movie used to many of their own methods. The goverment in the movie is what the american-gov will be in a few hundred years.
IMHO it is the best SF series i've ever seen. It's not the most hardcore sf - meaning it doesn't have 10000000 aliens running around everywhere and it doesn't take place a million years in the future. Actually imdb says it's also a western.
Here is the series' review - 9.5 is quite huge if you ask me.
Serenity the movie - is the least that could be done for the Firefly fans. The series being butchered and killed, they had to give some conclusion to the story, because the first season wasn't even finished.
It explains many things; but you don't necesarely need to see the series before the movie ... even tho it's better to view them in chronological order.
Here is the imdb about it. 8.0 out of 50000 votes is huge, especially for the outcasted sf genre.
