If anything, once the movie is done, that will free up Komaki and thats a big boost. Tho, i'm not sure if she'll direct any episodes for this arc, she might want to take a break after the movie.
As far as the episode goes i cant say i enjoyed much but it wasnt bad. Some shots were really cool and the Usopp-Chopper filler waa fairly enjoyable tho slightly dragged out. To be fair to the episode, i'm in a ep 1000 high right now and i watched the preview before the episode so that could have affected my enjoyment and investment for the episode.
Judging by the preview, 1000 is already a contender for most animated episode of the franchise. I hope to see a lot of cool ideas that go beyond just pure action. Or i guess some good old meathead action is fine too but i want to be surprised by the writing too, not just the aesthetics.
