I base these mainly on my enjoyment. While the story in the Chimera Ant arc is extremely well thought out, I found the build up to the palace invasion extremely boring, barring a couple of episodes of course. That's my main drawback with the Chimera Ant arc. Its' pacing is extremely slow, which means a lot of boring episodes. If you want my honest opinion, I enjoyed this arc the least out of any arc in HxH. Yes, there were definitely some fantastic highs, but it was a real slugfest to get to that point. The ending was absolutely beautiful though. Pokemon XYZ is a bit of personal bias since its my favorite Pokemon anime series (If I watched it today, I know I would rate it lower since I'm older). I thought Re:Zero sucked at first, mainly because Subaru was unbearable for awhile. It wasn't until episode 13-14 that I actually started to enjoy it. I actually just increased ToG from a 6 to a 7. I think it is better than I give it credit. Haikyuu latest season was somewhat underwhelming, at least compared to the other seasons. MHA S4 was not the best. I thought Beastars was good, but I didn't like the last couple of episodes.
