I chose to watch the first episode of the Firefly series by Joss Whedon. Although not incredibly unique (space westerns having been done several times before,) I find the delivery fascinating and am intrigued to watch more.
My favorite aspect of the show was how they attempted to integrate the chivalry of the cowboys into the captain by making him a former soldier. Having been a soldier means that he has a dark past, and gives him some violent, rough flaws. Those characteristics prevent him from being a perfect character, which is typically harder to sympathize with. The captain's loyalty to his crew and willingness to murder men in cold blood over it is nothing short of fascinating.
I am also a fan of the shows dark, dry sense of humor. While much of the humor revolves around the sarcasm found in bad situations, it is not done in an overbearing manner, much to the credit of the actors. I do believe my favorite line has to be the simple “Well maybe I'm not a fancy gentleman like you, with your... very fine hat.” While obviously a sarcastic statement, the captain says it with a completely straight face, and has almost no sarcastic tone in his voice. Another fine example of their humor is the *spoiler* anti-climactic gunshot that kills the federation officer in the middle of his speech. It was done so abruptly and callously in a very tense situation, and resolved a plot-line so easily that I couldn't help but chuckle. Whereas most shows would've had the officer at least finish his speech, Firefly simply killed him off, and left it at that. All in all, I'm rather excited to watch the second episode.
