Think the Terminator break every bone in Matt's body?

Yes.

I am sure there were some bones that were still intact by the end. Breaking every bone would only be possible with a meticulous and methodological beating, if the aggressor keeps trying to do this exact thing for the duration of the battle.

Teeth are also bones, so are you saying his every tooth was broken as well? Not even one stayed intact? There are hundreds of bones in a human body, it's not likely that such a chronologically short beating, where 'breaking every bone' wasn't the goal, could've resulted in _every_ bone being broken, it's way more likely there were actually several 'survivors'.

I'd argue Reese's was just as Brutal.

That would be something interesting if they were and there was footage of Matt smashing that Lamp over the Terminator's head. That would prove the Terminator wasn't human.
