This review has Spoilers. Let me start by saying that the story was poor but the animations and fight scenes were really great. Watched it on Netflix on 1st October 2021 and seriously the story was crap Story (3/10) Just like season 5 this movie too didn't had any story. I just watched it for sake of the name and since it was the last for this anime and now it has finally completed. The things that troubled me most was that Merlin and Arthur didn't had much of scenes in movie and in last it feels like the story isn't completed Art, Animation, Sounds (10/10) The best thing this moviehad to offer were the cool animations and real good sounds.
I am a little disappointed since the movie didn't had a great OST and Perfect Time Ost was used.

Characters (10/10)
Really wanted to see Merlin the traitor but sadly she wasn't there and the time she had a scene the curiosity piqued and the movie ended. But it was good and all the previous characters were there.

Enjoyment (10/10)
The story was crap but the animations and sounds were awesome so I enjoyed it. One can also say that I enjoyed it because it was the last nail of coffin for seven deadly sins anime.
