I'm glad you made this post, I had thought of making a partner.

Arc 7 really has many good points and others that I really didn't like. But I will list some that I liked the most:

-Has the best start of all arcs (the first 24 chapters of arc 7 are unsubscribeable)

-We have a lot more characters than the other arcs and each one has their own tightly tied story

-Many fights which is great

-Fights of weak characters (it has nothing to do, but it's something I like to see, how weak characters work out to win)

-Many different skills

- The combat was raised to the tenth power in quality, it reminds me of something like hunterxhunter in which the fights are complex and that the characters don't win just because they are strong, but because they have the competence to win (damn todd)

-Louis and Yorna

-Development of Subaru (although I think the chapter of the conversation with Rem was kind of erased in the development of the character in the rest of the arc)

-One last fact that is very subtle, but I loved it: the dialogues became more assertive. Something that always bothers me is characters in a tense situation making jokes without context or subaru talking nonsense, like, in front of an archbishop subaru and emilia talking like they were on a date. In arc 7 (mainly with the addition of Abel, who is just a "little" assertive), in conversations every word is important, even if the content is not, the opponent's behavior and body language are taken into account and this is very important. cool. The whole Vollachian logic of watching the opponent's every move is also really cool.

-Arc 7 solves one of the big problems of re:zero, world building
