Well I watched the past two episodes.
Episode 14 was okay but the fighting was awkward in regards to Levi vs Zeke while I enjoyed the scene where Eren beats the shit out of Armin because Armin calls out Eren for being a slave to his ideals whereas Eren literally gets triggered by Armin calling him a slave that it's funny and Floch's shit was funny as usual.
Episode 15 absurdly had better animation despite it just being Zeke's backstory and it was honestly more well done and is handled better compared to the manga's rendition of the backstory. Honestly the anime made Zeke's motives stronger while also helping show stuff that makes Zeke's turn around in 137 make more sense.
Looks like the cliffhanger for Part 1 is going to be Marley's invasion of the Island.
