It is pretty straight-forward that the new Terminator Genisys is going to turn the whole franchise upside itself. When the first trailer was released a couple of months ago, we figured that all points in time were focusing in one moment. Now, it seems that everything is worse than we originally thought.
The big reveal in this trailer is that John Conner has become what he was supposed to fight against. Sarah knows who Kyle is and there is an older Terminator waiting for him. Not only that, there is a new T-1000 and the whole John issue.
The timeline with the franchise has always been a bit confusing but this throws everything at you. I can only imagine that it will be more confusing when the film comes out this summer. This is the last batch of films that are supposed to end before the right revert back to James Cameron. God help us all.
