This isn't just a teaser trailer. This is co-writer/director JJ Abrams saying "Look - you can trust us. We know what was great about the originals and what was bad about the prequels. Our movie is going to have some of the good stuff you already know...and plenty of really cool stuff you don't. We're not going to let you down."
We'll see. The execrable PHANTOM MENACE also sported a damn good trailer, the release of Episode VII is still a year away and there's not a great deal of footage on show here. But what there is - the X-wings flying over water, that lightsabre/sword hybrid weapon, the incredible Millennium Falcon shot - is enough to give me a new hope about the direction Abrams is taking.
