Curiosity: they never did explain why the Enterprise needed to hide in the ocean on Niburu. It would've been nice to have a reason for hiding a starship there. I know the real world reason was to give it a grand reveal to open the film, but an in-universe reason would've been nice.
Hey, here's one for you: how did they launch the shuttle underwater? Unless I'm mistaken we've yet to see an old-fashioned Star Trek force field of the kind that lets ships pass but keeps air inside a shuttle bay. So they just opened the clamshell doors and...what? Where are the water pumps?
