Vol 1 and 2 are mid, vol 3 is great, vol 4 is fine and vol 5 is great if you love character moments and develop over cool fights, vol 6-8 the series just keeps getting better
This is a rare opinion. Never seen this kind of ranking for RWBY volumes.
Vol 1 admittedly is a bit of a rough start, though that applies to a lot of shows.
Vol 2 was when the show really started to pick up for me, and I really started enjoying it.
Vol 3 is clearly the best.
Vol 4 is a little underrated in my eyes. Weiss' development was great. I just wish everything else about the volume was as interesting.
Vol 5 left a bad taste in my mouth, though I don't hate it as much as I used to (I still heavily dislike it).
Vol 6 is very hit or miss. Some episodes are good, some are bad.
Vol 7 was the best volume since vol 3 imo. Ironwood's character was amazing, and there were a lot of interesting dynamics, though I do wish some of the stuff were better executed, like the fight between Qrow, Tyrian, and Clover. That shit was ass.
Vol 8 started off good, but took a massive nosedive towards the end. Idk wtf happened there lol.
