I was really excited for the Barto filler because you know it was Barto and we haven't had filler in a while, BUT to my disappointment, it was just a recap of Wano to Raid on Onigashima with Barto and O-Tama. No new content just recap, It was just O-Tama telling Barto what Luffy did in Wano and Barto reacting. Highly disappointed, I at least expected some random side story, not recap. Barto and O-Tama were drawn in chibi form which I thought was pretty cute. Barto didn't do much other than react to O-Tama telling him what Luffy did in Wano so I think itshould have been called O-Tama something and have Barto as a guest
