My favourite movie would be "Your Name" adapted from the novel, you guessed it, Your name.
Every moment in the animation is precious, this is outlined by the amazing art produced, also key moments that make you contemplate what you're and what you're going to do are deeply embedded into this. Almost without uncertainty, I love this film because of its romance, it always sparks me how two people can have so much trust in each other that they are willing to sacrifice each other for the sake of the one.
