It's a pretty good trailer. I've enjoyed the last two films for the sheer spectacles that they were, albeit the second didn't really feel like it started going 'till the end. If this last one is any good, it should make Dead Man's Chest retroactively better. Or if it sucks, and doesn't tie up a lot of loose ends or expand on certain characters (Davy Jones), it will be make Dead Man's Chest retroactively worse (a la Matrix Revolutions).
