Host ★★★½

This is actually very well done, considering its restraints, and restraints are often when the best horror is made. I don't know how I would have reacted to this during the Zoomiest parts of COVID, but it still works. In the filmmaker's favor, all the actors feel like real friends (b/c it turns out they are), but there's also plenty of knowing tech-based humor alongside the genial humor of friends being friends (like doing a shot any time Astral Plane is mentioned). Technology glitches wind up giving not just good scares, but some of the film's best surreal moments (the repeating background in one woman's screen, the face-recognition algorithm going off when you least expect it). Highly recommended and *not* to be confused with Unfriended, thank you very much.
