While me and my friend is checking youtube for tutorials, he stopped on this anime called "Playing Death Games to Put Food on the Table". The title is catchy and the animation is different than others. The comment section is very positive as well but then, he checked on this one part in Episode 11 much closer and something seems off. It was so obvious that he had to check it multiple times and show me that as well and yes, it looked very wrong.
I don't know this anime and haven't watched any of it. The no face and looked like watercolor style without the lines doesn't appeal to me as well. However, this one particular part, I don't know if they just missed it but even if you watch it on normal speed, it looks really bad and obviously wrong. First, the wrists doesn't touch as you can see. The second part is the knife is on the background beneath the right arm when it should be on the foreground or the hand should be behind the knife. To me these are very obvious mistakes and it shows.
I don't mean to make a big issue of this but I feel like recently, the quality of animation is going really bad and I don't know if AI has anything to do with it since I don't know if they used AI with this anime. I haven't seen any information about them using AI.
Here's another one from One Punch Man Season 3 that I suddenly remembered.
