Ethan Colburn’s review published on Letterboxd:
I've never seen a movie that expresses my life philosophy and anxiety so accurately. This movie expresses the chaos and loneliness of feeling like the universe has no meaning, but the importance of assigning that meaning yourself.
In contrast with Interstellar, which felt cheesy when it explained why love was essential to the universe, love is important to this universe because it is important to its characters. Rather than love existing within black holes, our loved ones can create black holes to represent their emotions. The film's absurdity serves to externalize the fears and desires we feel every day.
From a technical level, it is amazing how well the movie navigates its own absurd world, and gives you so many emotional payoffs. There is a good amount of exposition early on, so near the end, the filmmakers can transition seamlessly between worlds and universes. It is truly Hitchkockian the way the filmmakers have you in the palm of their hand.
Please see this in theaters if you can. Seeing this for the first time with an audience is an unforgettable experience.
