Well, it was bound to happen sooner or later... Firefly filk. Someone's taken the theme song from the TV show, used it as a chorus, and written verses around it to produce "Mal's Song." Now, maybe it's just me, but that character really doesn't seem like the folk-singing type--
MINISCULE SPOILER FOR SERENITY BELOW
--I'd rather hear "Jayne's Song," since we actually see him sitting at a campfire and strumming a guitar in one scene from the upcoming movie. And we've already seen him singing in "Jaynestown." Wouldn't that be more entertaining than some loser whining about how The Man is out to get him? Yawn.
Not to diminish the filkers' efforts, but I still prefer the original, without embellishment. Sometimes, less is more.
