One of Summer Glau's kickass fight scenes from Serenity. Bit of advice... Don't mess with a girl who can stand in front of you and kick you in the back of the head at the same time.
WHY THE EFFING EFF DO PEOPLE HAVE TO RUIN PERFECTLY GOOD SCENES WITH THEIR CRAP MUSIC TRACKS!? Filmmakers labor long and hard to get music and sound to perfectly match image - trust me, I do this for a living. This is an abomination, I don't care how good the song you pick!
