This is a great adaption so far based off one episode. It takes about 4 or 5 chapters of the manga and tries to string them together as if they are all happening simultaneously. The two main stories in episode 1, the Dad's spiral problem and the girl with the crescent tatoo, are completed in this episode but they also throw in the spiral boy that goes to school and add some of the Mom chapter. I can already see the chapter they are going to pair the rest of the Mom story up with and I'm excited to see how they do it.
If you don't know what I'm talking about that's fine, just know these stories unlike the manga are now all being told next to eachother instead of the primary focus of each chapter that they were in the manga.
This... is an interesting choice. I think they pull it off fine. It makes more sense that these things would be going together. Unfortunately this makes the series seem rushed, and at 4 episodes you know there will be some cut content from the manga. So how much is cut in episode 1... well not much, almost everything from the first chapter is in there, but with so many things going on it feels rushed.
Animation, sound, and voice acting are all top notch, so despite me feeling the series is rushed I"m looking forward to how they weave everything together as they move on.
