All I know for certain is that whatever master mind in Hollywood said "Hey! Let's make a movie and put a sweaty Christian Bale in it and a sweaty Sam Worthington in it for the ladies." He (or she) is a genius! A FREAKIN' GENIUS!
I mean, just look at him... Christian Bale could be in a movie about killer zombies with prosthetic legs and a desire to make all human beings purple and I would go see it. Yes, I would.
Now if you will excuse me... I have to go see if John Connor's pregnant wife ever has that baby and if so, does that mean there will be more Terminator movies to make me confused and turned on all at the same time.
God I love Summer Blockbusters that make no sense!
