Yeah, it's probably not the best-constructed trailer we've seen, but the footage itself still looks great I think.
There was one slightly iffy effects shot where the Enterprise had a brighter, golden look for some reason. But everything else looked fantastic.
I just noticed that on a second view. It looked like the ship was Brown. Hopefully on the finished version this is something they fix. Not entirely a big deal, but hopefully they caught it.
No no no! That's PART of the episode guys. The Enterprise is bathed in the light of the star from "Half a Life". Here are the original caps: http://tng.trekcore.com/gallery/thum...lbum=95&page=3
