Favourite: Past Lives. I hate mediocre romance movies. But when they are as good as this one... they are some of the best cinematic experiences I've ever had. Past Lives is right up there with The Bridges of Madison County and La La Land for me.
Worst: The First Slam Dunk. What a pile of dogshit. It does not only offers a vastly inferior version of the last arc of the manga (the base of the movie), but it completely butchers and disrespects 4 of the 5 main characters in order to give some background and relevance to the 5th one (which I'll admit was underdeveloped in the manga). And the ending... my God. It was the Rise of Skywalker all over again. I left the room when I saw where that was going.
