I'm not a big fan of the direction this torchwood is taking, it stresses me and upsets me, but it is torchwood and it is Captain Jack and Gwen Cooper, so I'll keep watching it.
I was wondering when they'd bring in incineration as soon as I saw the splat-man that somehow was not incinerated by his own blast and when they shot down the helicopter. It also made me wonder why they didn't try to see why they couldn't just take out the brain and put it into deep freeze. After all, if it is the body that is destroyed and impossible to repair, and yet every cell carries on living; it stands to reason that the best way to alleviate the constant pain of people who have suffered terrible trauma would be to remove their brain and put it into a deep freeze until a technology can be created to clone them a new body or build them a new robotic body (Yikes! Cybermen!) Brains / heads are much easier to store and catalogue, as well. Once the head/brain has been placed into the deep freeze, the remaining body could be incinerated (transformed from living tissue into carbon) or dissolved in acids (reduced to their component chemicals... (Soylent Green is people! It's peeeeeeepullllll!!))
Also: Brain death? So every cell carries on living regardless of the circumstances.... Except brain cells? After all, brain death occurs when the brain cells, starved of oxygen, actually die. They actually mentioned on a couple of instances that some people are now just vegetables or are brain dead. That seems to go contraflow to what they've been saying the entire time. I understand that that is just part of the BBC sci-fi package and I normally ignore it, but in this show it bothers the heck out of me.
