That whole scene wasn't necessary.
Star Trek as a franchise isn't "necessary" - what's your point?
The impact of a faster than light object with an atmosphere should have been dramatic. Like a mach 3 jet hitting the water. There should have been a shock wave....
Yeah... well... you know that in Star Trek the ships don't actually move but bent... no... warp the space around them to reach their destination... except when they actually do move...
Oh well, it's Star Trek.

Isn't that what Abrams was trying to do....RIGHT? Dramatic....and he MISSED...on the one part that would have worked to that drama style...
That scene, the visuals actually were quite dramatic just the way they were.
And did you see what they did with TITAN's atmosphere when it emerged? It was like the atmosphere was made of the heaviest and high density gas....at the border...of a vacuum.....
It really does boggle my mind the choices he made....
Who ever said that this was a choice made by Abrams?
That shot looks more like the particle-system was set for "faster rendering"
