While T2 is fantastic and still remains one of the best if not the best action film ever. It also in a way destroyed the series. It was too good and too successful that they had to make a million sequels chasing T2. All with the same bland idea of Arnold protects and new model is bad guy. T2's once novel concept is more tired and worn. T2 is a slick film. T1 felt original (tho it was a rip off of a book and episode of Outer Limits) T1 had that great gritty 80s feel. It felt more like a horror film. Since I was a big 80s horror fan and sci-fi fan. I'm going with T1.
