What was the point of this film?

Rating: 4/10 (12 August 2013)

*SPOILERS AHEAD*
I just don't see why they made this film other than financial gains? I mean it's no classic, it doesn't break any boundaries, it barely even has a plot,when some interesting ideas arise nothing great happens from them? It's very clean, the cinematography is amazing, it's visually quite stunning!! It has a decent cast? Yet they decided on this slow paced nothing story?? WHHHHYYY???! So earth got destroyed....the alien robots wiped everyone out....so now humans are living in space but they need water etc from the earth, so they need human engineers to guard & repair machines/drones....but it would be way more logical to have repair drones repairing the attack drones no? Considering how far in the future this is I'd assume the A.I in the repair drones would suffice?! But no apparently not the machines are conveniently super smart when the writers/director needs them to be yet completely stupid & clueless when they don't want them to put another hole in this sinking ship of a plot...if you can call it a plot? It had one good idea when cruise's character realises that the radiated zone is in fact fabricated & it's just to stop him seeing himself (cloned) this was great & a big sort of moment in the film but then he beats him up ties him up goes to the 52tower to then return & tied up cruise is gone but it's never mentioned as if by magic? Then if that's the same cruise that helps Freeman's character at the end why would he even help? He isn't then in cruise character & suspects nothing right! Or wrong? Argh I don't even know & I don't care! Just thought I'd share some thoughts on what could have been pretty awesome yet turned out to be totally pointless?!!!
