It was not that the pilot did not know how one worked, it was that he did not know how one looked. In all Sci fi show a wormhole looks like the thing the Tardis travels through in Doctor Who. Interstellar used folding space instead of the wormhole. Probably 95% of the population does not even know what folding space is.
Ill give you throwing out all science at times, like what happens when he goes into the black hole. He should of been crushed and or burnt up long before he even got close. That disk that goes around it is super heated gas. His metal ship is ripped to shreds, but he is ok etc. Or how he "programmed" a watched while not actually being there to do so.[FONT=Verdana][/FONT]
The old people are part of the story, it makes it feel more real like a documentary.
But could of been a lot better if they stuck to actual science and did not go off the rails, that is really what got to me. I'de have given it a 9/10 till that part. But due to going off the rails 7/10.
