And it's absolutely pitch perfect. I'm sort of stunned by how eerily accurate it is.
It's accurate to the point where it actually uses the audio track from the movie itself and it fits in perfectly. Brilliantly edited.
It's also a testament to Grand Theft Auto V itself or, more specifically, Grand Theft Auto Online. My only complaint is that you can't have two people on a motorbike, so you can't replicate the whole 'John-Connor-driving-while-Arnie-shoots' thing, but it's a minor quibble in the grand (theft auto) scheme of things.
First thing I'm doing when I get home is watching Terminator 2.
