It's a shame they changed the story so much... The battle with the goblins looked way too easy compared to the original which took the entire guild to beat. They've missed so much out and changed so much compared to the LN and manga, but that's my fault for expecting it to be the same.
Isekai's don't always have to be amazing. They don't need to always have some deep plotline, a major reveal or something. It can just be a fun to watch adventure. If people enjoy watching this, don't shame their enjoyment of it. It night not be necessarily "good" but it's not bad either. It's neutral, and I really enjoy Neutral Isekai. Even if nothing is going on. :)
