The writer describes The Guest as Halloween III meets The Terminator, and I think that's a surprisingly apt description. This movie is part horror, part thriller, part comedy, and it absolutely nails every genre. While it may appear on the surface to be a typical "mysterious house guest" thriller, it's actually a loving homage to the horror/thrillers of the 1980s (before doing homages to the films of the 1980s was really a thing). A tense, compelling synthwave soundtrack really sets a good mood, and the acting and dialog is appropriately campy, despite everything being played pretty straight. It's a good time, well worth checking out.
