It did exactly what it was meant to do. It let you know that the movie is coming, it told you who all the main characters are and who was making the film, and how it ties into the Lord of the Rings Trilogy. Teasers don't give away any of the plot. I would've liked at least one interesting action shot (giant Mirkwood spiders, maybe Smaug), but since that will be all CG and probably isn't done yet, this is what we get.
