Trailer trash

I watched the trailer for Kingdom of Heaven, kindly pointed to by Sander, and it struck me that the trailers I have been watching lately bore me. They are so alike, so un-inspiring and all seem to be made by the same team of people. Alexander. Elektra. Boring. And that's a crime in an entertainment business.
There are good trailers out there. The Incredibles. House of Flying Daggers. And most notably Sin City, which must be the most stylish trailer in a long time. At least this one was not made but the team that churned out most of the other trailer thrash out there.
