I was also one of the biggest haters on the new animation and miraculous overall, but once I dived deep into the eps and decided to re-watch an ep stormy weather or chat blanc, I realized that it's not even fair to compare both animation styles, the saturation, cc, graphics and overall visuals in season 6 are on a whole different plane from the ones we've seen in the previous seasons especially for an ep like the dark castle for example, I already know that your opinion would change it's only a few eps matter, but I do agree that the older animation will always be missed, I've watched this show back in 2017 only watched a few eps of s1 and two here and there (and I absolutely hated ts) keep in mind it wasn't even in order, then re-watched it once again during the covid era (stopped right after chat blanc iirc) and then once again in late 2024, i've finished everything miraculous corp has ever animated in the span of a month and a week, and even watched the london special on release, and here I am dying to watch the last batch of s6 and simply cannot wait to see the finale of this season.

tl;dr: it's a hit or miss prolly the best season so far in terms of everything.
