I really liked it, and I thought it was cool to have a arc without Gyro, and Johnny. I also think Mike O is another very interesting minor villain in part 7.
It was nice to see them focus on Lucy and Hot Pants. Still not sure how she killed that guy. Like, what was with that? It was a nice arc. I liked the Catch the Rainbow arc. Blackmore's stand is one of my favorites in the entirety of SBR. To bad it requires whether patterns to be useful.
