I always thought The Hidden was an unjustifiably forgotten scifi action movie from the 80s, and this is reinforced by the positive reviews it got and still gets. Basically, imagine the Terminator meets Fallen - except instead of a time-traveling unstoppable cold-blooded robot pursuing/being pursued by a good human from the future and shooting up Los Angeles in the process, and a demon possessing suspects and detectives, they're space-traveling unstoppable aliens (one cold-blooded and one nice) chasing each other and shooting up Los Angeles, and taking over suspects' and detectives' bodies. It's more smartly written and filmed than you might expect from that description (I still think the intro is quite clever.) And, the good alien is played by Kyle MacLachlan, and one of the evil-alien-possessed-people by Claudia Christian, before she was in Babylon 5. You may also recognize Ed O'Ross, who showed up in a number of action/scifi movies in the 80s and 90s. A good number of one-liners are had by all, with a possible explanation toward the end of the movie of what's happened to our political system recently.
As a side note, that narration on trailers from 80s can sound so dated makes me realize how very old I truly am.
