Premieres sometime this year, likely with more information coming during AnimeJapan 2024 at the end of March. This movie takes place during the events of season 4 of the show. Synopsis of the first season from AniList:
The story takes place in the year 2138 when virtual reality gaming is booming. Yggdrasil, a popular online game is quietly shut down one day. However, the protagonist Momonga decides to not log out. Momonga is then transformed into the image of a skeleton as "the most powerful wizard." The world continues to change, with non-player characters (NPCs) beginning to feel emotion. Having no parents, friends, or place in society, this ordinary young man Momonga then strives to take over the new world the game has become.
I think the infamous baby "goats" and CGI soldiers really fucked my enjoyment of the anime. I read the source material and was so hyped for that part of the story.
That's fair, everybody is different. I think I have watched enough bad shows at this point that I have become able to let the weird CG animation roll off my back. However, when I started reading the source novels after getting caught up with the show, I just couldn't really connect with them and dropped them.
