Terminator Salvation hands down
when T3 hit theaters, I had 0 desire to see it as the previews just looked like a rehash of T2 (and judging from reviews I've read over the past decade, I was right on that assumption)
I have T3 on DVD yet I still have not seen it, not once.
at least Salvation had a but load of action scenes that were top notch, I absolutley LOVED Bale as J.C., all of the homages to the past films, Anton Yelchin (nuff said, excellent young Reese) and even though Sam let his damn accent slip through in a couple of scenes, he still did a decent job. (but he needs to control that if he's going to be a star in Hollywood, it does take you out of the scene when you hear him sounding American one second, and Australian the next).
yea, despite it's flaws, Salvation was still a "decent" flick and far superior to T3
