Great looking, but not in SFclassic league

Rating: 7/10 (12 August 2013)

Some sporadic spoilers ahead, so be warned. First some Questions for story writers that arise to me: 1. Why Titan? This moon is terrible place for humans. Granted, it has liquid lakes an rain, but that is liquid methane we are talking about! So, no oxygen, no water and terrible cold. 2. Why go thru that energy hiperintensive cost of destroying a Moon only to scavenge water from earth? Jupiter moon Europa is 100% COVERED with water! Why not go there and work in peace? 3. Why "scaws" at the start hide their appearance from Tom? Makes no sense. 4. So what is the deal with radioactivity? At first, there is zones, later it comes to conclusion there are false borders. After nuclear war? 5. Why all of the clones go to age of 50 Years old like main character? 6. Why mother ship cannot recognize nuclear warhead, but can tell if is main character lying by his breathing and heart rate? 7. If water is somewhat sucked up (as we see from all those scenery and big fusion stations), how comes so much clouds in the area? ........... But overall, it is nice bigbudget SF flick, experienced and proved actors, decent twist, and fx-vice; worth looking at big cinema screen.
