I am with Kermi on this one. Saw it in IMAX. Was a beautiful movie. Serious plot issues for me. Some of them in the fiction side of the science only where it didn't tie logically to the narrative. I can suspend reality for fantasy, but for example if you show me a Troll in a movie and tell me (in the movie) he cannot flap his arms and fly, and then he flaps his arms and flies without any further explanation.... well, that is stupid.
Little bit of a SPOILER below:
Only wheat, okra, and corn? What about every other staple food? Where is the livestock? Everybody is a vegetarian in the future? There is no dust in Hawaii. People can't live in Hawaii even? The radius of the ship at the end was too small (e.g. the baseball hitting the window). So many more issues...
