I saw this yesterday and I have to say I was fucking surprised as all hell to discover that this movie KICKED ASS.
I absolutely loved it, the ending was awesome, the interesting twist with the T-101's character was fucking cool...and it's nice to see that all the time paradox stuff that was created in T2 is now fixed.
Definitely a worthy movie, completely better than I ever hoped it could be.
That's a bit more than simply saying you enjoyed it. I always wait a few months to hear what you think of a movie, because it's usually a lot less excited sounding after a couple of months go by. :P
