Hard to argue with your reasoning, even though I do love T2. The Terminator's relentless pacing is one of its strongest features IMO whereas T2 is paced like an adventure movie or something. Also seeing Arnie as an absolutely ruthless antagonist is fucking amazing, The Terminator is basically perfect sci-fi horror along with Alien (*and The Thing).
I really enjoy the way it portrays the happy, poppy, dancing teenybopper 80's slamming headfirst into futuristic brutality. The scene where Arnie walks into the club and everybody is dancing around him too coked out probably to even notice his big ass gun aiming at Sarah Connor is basically analogous of what I'm talking about.
For a long ass time the original Terminator was my favourite so it's not like I don't see where you're coming from.
