Thanks, I picked the unobtainium issue: the tree is supposed to be above the largest deposit, but it doesn't float. The movie could have been longer: afterward

Thanks, I picked the unobtainium issue: the tree is supposed to be above the largest deposit, but it doesn't float. The movie could have been longer: afterwards, I misread the time, and literally thought it was only 1:42 long (not 2:42). I'd see a longer version, that setup motivations properly. A conflict for me was that destroying the tree was a terrible act, but looked really cool. Maybe it's because I was reading Xenocide (3rd in the Ender trilogy), but many of the ideas in the film seem to be in that book.
