Before seeing it, I heard how apparently realistic this movie was in being true to the science. Yet it was anything but. The whole plot nonsensical. Not the worst movie I've seen (would rate it 5.0 if it wasn't for the incredibly high rating). I know I'm nitpicking here but: A saturn rocket type take off, yet they are able to get off another planet with similar gravity with a tiny shuttle which already used part of its fuel for landing. The spaceship rotated to create gravity however that would not mean there is any in the middle section where most of the scenes are. Not even gonna bother going into the worhmhole/bookase/mores code thing. Interesting concept but rather weak story.
