Obviously with these movies you just kinda have to throw logic out, but some of the scenes were just wtf. When Marcus was fired upon by a Terminator earllier, and then let through later on was dumb, but I guess they did it to keep the guys robotness secret. And really, how does Marcus just stroll right through into the main room, and then when he's there only shuts down one thing instead of everything. "But his computer chip made him just lead John in instead of shutting down anything" Meh he was able to rip the chip out later, to excuse not to shut down everything at that point. And I assume Marcus is still alive, no reason he should be dead by just losing his heart, no reason he cant gt Johns and just repair it and have the machine use its back up power. Everything sorta just felt rushed at the end.
w/e though, still a good movie, I guess ill look forward to the other two.
PS. MFing Arnold Schwarzenegger FTW! Even if it was CG.
