In reply to Blue Straggler:
Hi blue,
Again, I'd disagree that the aftermath was a 'lets wrap it up' thing. When the 'reveal' happens I think it's still in the first half of the film, and what follows- the psychological reactions of the two sams, but especially Sam-5, is the core of the film. The reveal is not the main point, it's just the vehicle to generate the conditions for the study of the characters reactions to it.
And even knowing where it's going isn't necessarily a problem - again it's not that sort of film where it's relying on unexpected twists. It's watching the characters deal with the situation psychologically, and thinking through implications of that, that made the film interesting in my opinion
Or that's what I thought anyway, but I appreciate that these are just opinions....!
And I will definitely check out silent running
Thanks to posters for the comments on source code, will have a look , it's only 3 quid on amazon so can't really go wrong at that price....
Cheers
Gregor
