Hmm... I suspect the movie itself might be interesting, since it's Batman, but....

That has got to be the worst trailer I have ever seen.
That's why it is called a teaser trailer. ;)

Maybe you haven't seen them, but there has got to be worse trailers than that. Anything promoting Gigli or Ishtar for starters. ;)
Well, it didn't do a terribly good job of teasing. I've got to admit, if I had only watched this teaser, and not IMDb'd the movie itself, I would now have no interest in ever seeing it...
True. I'm guessing it was probably targeted more towards Batman fanboys like myself than any other demographic. ;)
