We still have the talking heads - the likes of Elon Musk - from the present day to give the whole a documentary feel, but now there's also detail, for instance, of the interaction between Greenpeace and a present day drilling rig off Norway.
I'm sure we're supposed to appreciate the parallels between the oil exploration and the private drilling company that's been introduced into the fictional drama on Mars. But as we concentrate more on Greenpeace, it really starts to get in the way of the main storyline. It also focuses attention on the areas where the realism from season one has taken a bit of a hit and political correctness has started to rear its head.
Take, for instance, the plot line concerning water. On Mars water is always going to be scarce. The whole mission would be obsessed with the practicalities of it: purity, freezing and melting, containment, recycling, litres per person per day and so on. They would discuss the numbers. They would go to whatever reservoir they had and they would simply look at it. But not in this version. We're meant to believe in water being transported in a vast pipeline, clearly modeled on an oil pipeline in Alaska, and supposedly 25 km long.
And that's before we get to the drama. It's hard to sympathise with the characters on Mars when the story is constantly punctuated by Newt Gingrich or Greenpeace warriors on their walkie talkies. And we're further distanced from the fictional story as quite a number of the explorers have English as a second language and their accents just aren't always good enough. Added to that, the script is fairly sparse and the dialogue not always convincing. Lingering "emotional" head shots are no doubt meant to compensate, and sometimes they do, but other times they linger a little too long in actors that aren't quite up to the job.
In short, they needed to be fanatical about the realism, the characterisation and the plot to justify the talking heads. They just about managed it in season one, but in season two the balance has tipped the wrong way. You'd need to cut out half the earth-based documentary footage, bring in two or three really good actors and review the science to fix this. As it is, season two is only worth watching for Sci-fi aficionados. Episode 1 - 4/10. Second season - 6/10.
