This movie as an action flick was good, and if you go into the movie wanting just that than you're good to go. But if you have several more brain cells or are a Terminator fan wait until this comes out as a rental. The movie leaves you with no emotional connection to any of the characters, and if not for Sam Worthington the acting would have gotten an "D". Honestly, the T-franchise has given us so much depth yet McG and crew seemingly decides to skip any script with any substance for the sake of action. Way to think outside the box, Hollywood.
Many things were just plain ridiculous, and at times I wondered if I was watching The Matrix. The little things made the movie unbelievable.
