Good watch, might watch again, and can recommend.
I have no idea what just happened, I just watched the 2020 version, and it doesn't even look better, and there doesn't seem be a lot of info on the situation.
It has decent practical effects, it's a got plenty of action in a machine chasing a woman aided by a soldier from the future.
Arnold carries an odd amount of weight as an emotionless cyborg, but Linda Hamilton shores up the rest. I don't think it is Michael Biehn's fault, but Kyle Reese is kind of a forgettable character in this.
The depth of this action movie is just on the concept of time travel, and whether or not you can truly change the future.
This is a good movie, but it lacks something really special for the time of 2020, it's more important as a precursor to the sequel.
