Terminator 1 or 2

[Vampyr]

Prefer 2 myself. Terminator vs. Terminator was awesome, and having Arnold as the good semi-bad guy was also very cool. Not to mention the liquid metal was an awesome effect.

One thing that I didn't like so much about the third one was that I felt that the terminator from the second was much more lethal. The third one had more firepower, but ultimately easier to kill.
