I watched this on release and took my 9 yr old son to watch it again last night.
He really enjoyed it and asked a lot of questions, some I couldn't answer.
I love the film, favourite so far for 2015.
It's looks incredible. It's engaging from start to finish. Certainly emotional on many different levels.
Another brilliant film from Ridley Scott IMHO.
I'm no scientist to argue the truth of many things that happen......for me it's a movie.
Will be a day one pruchase on Bluray for me.
