Terminator Salvation (Blu Ray)
As a stand-alone movie it probably wouldn't be that great, but it does a REALLY good job of continuing the Terminator saga and reveals a LOT of things that you see from all the way back in the first movie. Such as ... How John Connor get's the scars on his face and how he and Kyle Reese meet.
Lots of really good action and a decent story as well.
Fake looking "Ahnold" Terminator left a bit to be desired. Thought they could have done a better job with that.
If it's true that the next Terminator Movie will indeed be the last, I'd LOVE to see James Cameron involved somehow.
