The rumour doing the rounds about Terminator 4 may be ground breaking in the franchise but it's not anything new elsewhere, and while everyone seems up in arms about it screaming obscenities in comments and titles, I'm wondering if it's a script move that under another view might be considered rather clever.

Lets, if we may, consider an alternative project for a moment as a comparison of the plot twist and see if you suddenly realise that there are some hugely biased viewpoints out there. However before we do can I just say that this may well be considered to contain spoilers for a fantastic TV series as well as Terminator 4.

Let's talk Battlestar Galactica and the end of series three. Yes, I thought you might want to be turning away right now if you haven't seen it.

Let's talk about that huge season finale shocker where we see that four of the least suspected people aboard Battlestar Galactica are in fact Cylons. The moment that characters we've come to accept and bond with as humans all these series are suddenly revealed as the enemy underneath that skin.

You're already with me aren't you? That was a moment of scripting genius and provided a hugely shocking moment.

So let's just consider the Terminator 4 rumour from a "scooper" through AICN for a moment and believe it's real - because it could be totally false and it is one of those totally off the wall and film plot killing moments that so often are - but let's just believe for a moment.

Here's the rumour, and remember I've been going on from his announcement about the twist with the Marcus character being a Terminator.

"For some background, Marcus was a criminal who was executed in 2003. He donated his body to Project Angel which was involved with SkyNet. They take his body and make a terminator out of him so he's a terminator skeleton but has living muscle/skin and a beating heart too. At the end of the movie John Connor is fighting a T800 model 101 and loses. He dies and the top resistance people come up with a plan to help the resistance keep fighting on. The resistance feels that it's important to keep the image or idea that John Connor is still alive so the resistance keeps going. So they rip off Marcus' skin and put John Connor's on the skeleton so now Marcus is John Connor."

Why is the idea that we could have a huge reveal at the end of the series that John Connor will be a cyborg from here on and everyone will believe he's human be so wrong and be viewed as such a plot disaster? I think it's as clever as the Battlestar Galactica twist - it's a total turnaround, and why not?

We've already seen Terminators who have been made to be good, and all the resistance needs is a figurehead, why couldn't we be in on the twist from the beginning and know that John Connor is now a good Terminator leading a human resistance against the anti-human Terminators.

Although it certainly turns the entire story around on it's head from the previous franchise, it's as strong and as clever as the Battlestar Galactica series three twist.

However it's being viewed negatively because there are so many things stacked against it - the Terminator series has been going downhill with each new director, this is McG directing this one, and the Terminator franchise just couldn't be allowed to stray from what it's always been.

Personally I think this would have been a huge moment to see on screen at the end of the film, huge as in the same vein as Battlestar Galactica. So why is it being viewed so negatively?
