Visually clever but a bit daft when you think about it

Rating: 8/10 (16 January 2011)

It's visually very good and very cleverly made. The story's theme has been used many times before in other films but is quite cleverly adapted, in general, for a scenario in the future on a very distant moon.
Despite being set in 2154, with all the technological change that must occur to get people travelling 4.3 light years and creating living creatures with minds drawn from living humans, it seems rather daft that the humans still use guns with bullets and fly helicopters with propellor blades. Shouldn't the best science fiction be believable and not riddled with nonsense? Surely a physics trained writer like James Cameron should have got this right.
Isn't it also absurd to think that people will still be smoking cigarettes, particularly an eminent scientist like Grace? Is there really no hope that humans will abandon the evil weeds.
