Overall, I thought The Terminator was a really well-done movie – it was compelling and action-packed, with a genuinely terrifying villain. One thing I could have seen more of is details on the futuristic universe and Skynet, because other than Reese’s brief summary, we don’t really know much about it. They give the audience just enough information to understand what’s going on, which works for the purposes of this movie, but I think it could have been really interesting if they’d fleshed it out more. Both time travel and takeover by artificial intelligence are sci-fi clichés (although maybe less so when this movie was released), and so it didn’t feel like there was anything particularly unique about the dystopian world of this movie. Also, the ending, where it is revealed that Reese is John Connor’s father, works only if you don’t think about it too much – the time travel logistics laid out here are too shaky to understand how exactly this makes sense.
The other aspect that might have made this movie better is further development of Reese’s character and the love story between Reese and Sarah. He is one of the primary protagonists of the film, yet it didn’t seem to me that he had any personality traits other than wanting to protect Sarah. Giving his character some depth might have made the central romance more believable, because it felt slightly rushed.
