This is a very watchable movie from down under. Full of science lingo and tech jargon that's sure to please anyone interested in that sort of stuff, which I am. There was enough solid sounding math, science, and technology terminology to keep the film grounded in this universe though. The acting and overall production was quite pleasing given the low budget type film, which by the way was way better than most other low budget films I've seen. The overall premise of the film was solid and had good mystery and fulfilling drama with characters trying to solve impossible problem, working out the details to get problem solved, animosity and confrontation between characters, family drama, character flaws, compromise, global impact, etc, etc....The script was also brilliantly written given all the math and science lingo that went into this film, plus it moved at a good pace so you didn't get bogged down to much in any one of the plot points. Although a little bit of the acting was cheesy, most of it was very good and I never felt like fast forwarding or turning it off. Plus none of the characters committed the ultimate sin of 'people doing totally unrealistic and stupid things that nobody in any frame of mind would ever do'. I hate that type of drama, which is rampant, and I start yelling at the TV. Those writers need to scratch their heads a bit more and make it more believable. There was none of that in this film. The production was also very high given the budget and the props and technology displayed were spot on and led to the credibility of the film. This is a film you should see if science and technology are your thing. Way to go.
