Terminator(first one) was just starting as I was channel hopping the other night, so gave it a watch as not seen it for decades, was pleasantly surprised at how enjoyable it still is.
A sort of flashback sci fi chase slasher movie with an (interesting for its time) easy to follow plot with great pacing, an intimidating baddie, just enough special effects, identifiable characters, and a cast that have mostly gone on to successful careers.
Goes to show, with a decent director and the above ingredients, this type of easy to watch entertainment has a deserved place in movie history, its nearly forty years old too!
