All the episodes not counting the last are the same: Tanjiro goes to a Hashira to "train", every single one of the fodder hashira's look at him in awe for how good he is, Tanjiro doesn't learn anything, leaves for the next hashira. This is probably one of the worst training arcs I have ever seen in anime, it might as well have been filler, Tanjiro doesnt learn anything from this training, its useless.
And for those who say episodes like this can build characters up, very little of that is actually done during this arc, the pacing is terrible and the time is very poorly used.
Honestly you can just watch the first and last episodes and very little is lost, you're going to save yourself a lot of annoying "banter", specially the scenes with Zenitsu.
The last episode is the only praise I can really give this season, it has great action and high stakes, even if the outcome is pretty obvious.
