I think this is the first time I watched the tv series followed by the movie, as I’m pretty sure I watched the movie having not watched the show. I think it works well as a stand-alone, although why anyone would want to only watch the movie when there are fourteen fabulous episodes of quality TV is beyond me. This is the movie where I learned Joss Whedon never gets overly attached to his characters.

(wow, do I not like this poster. The other two were not good either.)
