The best game I could describe as merely an interactive movie has been The Quarry. The game itself is pretty meh (but I’m not a big fan of these personally), however the movie part is amazing. It could easily be just a kick ass horror movie. And you can even play it that way with Movie Mode, where you pick the best outcome, the worst outcome, or set up some sliders to give a mix of outcomes at every interaction and just watch shit unfold.

Detroit: Become Human is also in this vein, with an even wilder array of possible outcomes as well as some more real gameplay and puzzle solving.
