Do you guys think this monster world arc has gone on for too long than it should?
Nah, it's fine. To me this arc is one of the best just for the fact that it's in another dimension where even fucking air is dangerous, perfect place for MC who needs to grow his powers.
Also WW said that originally the monster arc was even longer but he wanted to cut it more short
Imo it wasnt necessarily too long, i think it was good to kinda establish the group and to have them share a lot of time together.
Buuuut ... imo it lacked meaningfull and satisfying fights with monsters or encountering anything really. The mc attained way more knowledge and power in the "dream world" while being in the monster dimension.
They have been there for such a long time (close to a year?) and nobody evolved and really achieved any meaningful power development (the mc's was more in the dream world) or evolution (michael go his now as it looks like).
It was a bit too much "were driving around in a carriage and do nothing but hide", they could have explored more, attained more useful and rare knowlege which could have given them a advantage when they are back. So i kinda consider it a bit of a missed opportunity.
And i cant lie, i want to be back on earth as fast as possible now lol
