If you go into this movie expecting quality of the first two movies....of course its going to suck. That being said, I enjoyed this movie much more than I thought possible. The recreations of the scenes from the first movie had me nerding out, bad John Connor worked for me....so did the Asian T1000.
This felt like a true sequel to the first two movies, and I wouldn't be mad if they made more. I may be in the minority here.
