The first difference between good old terminator movies and this one is that they showed us the killings back then, and now we're watching some film for babies where death is out of the screen, it's boring. The second thing is why the chronoportation wouldn't bring a strong wind while earlier it would?
Why do they got here so oldlooking mobile phones?
What's this? When John hit the car by the vet's van it was still dark on the street and the next moment it's already a bright day!
Oh yeah, I almost forgot! Why the machine made by the other machine (terminators) needs to have an understandable by humans interface? Does it need an interface at all?
