Completely unnecessary recap in a super slow-paced and uneventful anime.
Was painful to watch.
Sure, Art and everything is good - since all the scenes where from previous episodes - with the only addition of eventual commentaries from Kirito.
If this was an anime with a complex/deep plot, or even with a medium to fast pacing, this recap episode could be useful. But in a show where you can summarise everything that happened so far in three to five sentences - what Kirito does in the first minute of the next episode - it is completely unnecessary.
If you didn't decide to come back to SAO Alicization after months without watching, don't watch this episode.
