Emoticon-wielding Automaton spells out obvious plot

I watched Moon the other day, and whilst being an excellent film, I take umbrage with some of the finer details of the plot.

It adds to my "ye gods, did you actually give this plot any thought?" list, most recent of which was the plot of Batman: Begins - which had a device that vaporised water many feet away, but miraculously ignored all water in the human body of the operators stood beside it.

Anyway, let us return to Moon - if you haven't seen it, do, it's entertaining - then come back here.

So, we open with Sam Bell coming to the end of his stint on the Moon doing his thang - but something turns interesting. He starts hallucinating, seeing people from his memories, but on the Moon he's only comforted by; watching old TV shows, a worn leather chair, a table tennis table, a robot companion (who expressed through a massive 7 emoticons - a record for Kevin Spacey), 2 lunar rovers, and a job. All very "normal"... still he potters out to do something and crashes because of the hallucination.

Suddenly, Sam Bell awakens in the sickbay - not a scratch on him... and being denied access to the external aspects of the base kicks up a fuss. Eventually the automaton lets him go, and he buggers off to the crash site - why? Did he remember it - no... but you don't know that. He finds el-corpso previous version of him and brings it back to base... then we hit a long drawn-out hand-wringing explanation of what this is... ok lets look at this without our film goggles on, what are the options:

1. Time travel - where from? There is not future for el-corpso, so it's balls.
2. We're super-duper robots with all them skillz... if I could make the emoticon-wielding automaton, why would I bother with robots?
3. Cloning... ye gods, no, who would have thought of such a thing... I mean characters playing the same part - this isn't Last of the Summer Wine is it?

So, we've established the obvious - now we play the obvious out... the two meet and enjoy a game of wiff-waff...

Hang on, table tennis... but one person is assigned to the base, table tennis... doesn't that involve two people? Oh, hang on, there are two vehicles, two space-suits, two seats in the vehicles, but only one set of slippers... and we're lead to believe the company is doing the clone thing because it's cheap...

Did nobody perform any accounting on this outfit? Did nobody notice their moonbase costs where drastically reduced because they never went there? Did nobody notice the lack of launches? Yeah - take that Hollywood - accountants will crap over your plots from a great height... I accept Lunar Industries: The Dodgy Accounts may not have been as glamorous a film title - but still... how much am I expected to disbelieve?

And, after all the completely obvious plot points, the emoticon-wielding automaton felt the need to spell it out even further at the end of the film, in case you were so stupid you didn't understand.

And, if you didn't understand, never come here again.

Gah.

Gah.

Gah.

Visually fantastic, and loved every minute though.
