Am sure Ah-nuld must be kicking himself after seeing the end product.
Dull, lifeless and slow-moving, which could have been an action-packed whodunnit. Surprising to see accomplished actors like Sam Worthington & Terrence Howard in this, when there was nothing much to do for either of them, specially the latter. And that ending, both of them, didn't make sense at all.
Avoid, unless you absolutely have to see the Terminator in his 70s sleepwalk through a snoozefest, laced with some action and gory sequences which are few and far-between.
