I got into the Smith's[whole family was involved] "After Earth" enough to see it twice before the locals pulled it to make way for Man of Steel. As much as I'm a Trekker, I enjoyed this more than STID, at least the story was original only one glaring plot hole... evolution doesn't work that fast. Though many professional critics missed the point, WE frelled up the Earth, left it poisoned and barren and leaving all other animals to fend for themselves, it made some sense that simians would attempt to fill the niche left absent by humans and their hominid predecessors and since the air was poisoned when humans left, hence the need for breathing assistance after generations of living elsewhere.
Cross-mating of lions and tigers [normally not from same land masses but you need to account for zoo escapees/releases]to produce the hybrid we saw on screen as some owners have done in captivity, avian recessive genes in birds' of prey resurrecting the Roc of legends past, perhaps using South American Condors as a base species, adapting to the dirty Earth. Not to mention the plant adaptation. That super volcano in the distance wouldn't help much either.
Remember, Yellowstone Park is a caldera, there is primitive life deep in the seas now that exists around sulfur spouts
that was never believed in until relatively recent deep-diving instruments/cameras revealed their presence.
I give the performances much higher praise that the pros ever did. ....9/10
Unlike Oblivion a few weeks earlier, while visuals were nice, the big plot hole for me would be why would any sentient
machine pick on Earth? Other than to advance the plot?
It would have been easier for the protagonist to park near the sun [or any sun] for energy. For fusion reactors, it would have been best to park over Jupiter or Saturn [ plenty of free-floating hydrogen and helium] because it takes energy to split H2O into its' component gases, easier to make water when hydrogen and oxygen are present [ via an electric discharge] Ditto for Neptune or Uranus if gravity wells are a problem, the moons of the gas giants also have plenty of hydrogen and helium, some in frozen form as well as methane[complex hydrocarbons ie 'natural gas', used by the atom,rather than burning, could support as fusion fuel as well]. 6/10
