I figured we'd see it going the other way eventually, but that never happened. I guess because they wanted to establish the visual of right to left travel as shown for the rest of the movie. Where Enterprise flies left to get to Yorktown, then the nebula was largely to the left of Yorktown, then once through the nebula, the planet was to the left, etc.One other thing as I think about it, I was a little startled when the Enterprise's warp effect on screen was in the opposite direction as it was shown in commercials or the trailer.
