Get Out
Not sure which ending I prefer. The alternate one is more powerful, but the canon one is more satisfying in some ways. Regardless this was a great movie. A lot of thematics that are still relevant to this day. Strip that away and you still have an intense and creepy movie, ever getting too dark; it's a horror movie I'd feel confident in showing my girlfriend, or maybe even my parents.
The only criticism I have towards Get Out mostly comes down to my own taste. It never truly captured me the way I wanted it to. Still, it's a very enjoyable and entertaining movie with great themes.
