I saw it today, and needless to say it was utter crap aside from the special effects - easily the worst film I've seen since 2009. Basically it's just a high-budget action film with an environmentalist theme, which was so stupid that it almost sounded like Glenn Beck doing a parody of environmentalists.
(ex. The guys whine that humans don't respect life, but turn traitor and murder their fellow Marines in cold blood just to protect a magical tree which is basically the alien equivalent of the Internet).
But then I got to thinking. The film was produced by NewsCorp (Rupert Murdoch, Fox News), so what if the film was actually a very subtle parody of environmentalists. I mean as stupid as PETArds are, I find it hard to believe that they would make a film this stupid, or that NewsCorp even would release it - unless it was intended as a parody all along.
If so, then this might be the only redeeming value for this pile of no-talent garbage. Discuss.
