Who runs the world? ( girls! ha

..i digress) Is there an Earth president or is the president in Elysium the president of the Earth and Elysium population? I want to know who controls what to be honest. Regardless, is there no more democracy anymore? Why can just changing who the president is in the Elysium system actually change who the president is. Wouldnt there be an uproar?
This leads me on to the next point. The president saw Spyder and Max reboot the system and change the citizenships/president...so wouldnt he just change it back as it had been sabotaged by a group of criminals?
I know that the Armadyne guy reprogrammed it but if (as we are led to believe) "what the computer says goes" then the Armadyne guy basically controlled Elysium ( and/or the Earth

)
Also, Kruger coming back to life annoyed me. if you can bring people back from the dead like that, why was no attempt made at saving the Armadyne chap? We saw at the end that they had copius amounts of medical shuttles that automatically went down to save citizens...so why didnt that happen or why wasnt that put into motion.
Furthermore, why do they have all those medical shuttles? We saw that everyone in Elysium had there own medical pod that cured everything so what were they for? Presumably they were only built to service Earth..yet they were not used until the end. This would further mean that Elysium had **** loads of spare medical pods sitting about but just left people on Earth to die. What has happened to humanitarian aid in this goofy world?
*and breathe* I still enjoyed it as a bit of sci-fi rubbish but it certainly wasnt very clever.
