As for me, just happy to be hearing more Brook. "I love you Chopper" was absolutely perfect!
This. I really liked Strong World because Brook has a couple really cute moments in it, but Film Z has him even cuter! I just love that whole thing with him trying to get to bathe with Robin. And later his comments about the clothes he picked for everyone and how they look on him.
I was a little disappointed in Kizaru's voice, though. Maybe I just don't understand the meaning behind the way his Japanese actor talks, but the English actor didn't seem to have the right tone to him. Not entirely sure how to describe what it is that seemed off, but it didn't give me the same feeling about Kizaru that I got when I first saw him in the main series.
Did Luffy pronounce Akainu's name wrong? I don't remember how they pronounced it in Japanese, but it always sounds really strange to hear Luffy say it in the English dub.
This movie has also led to me developing a small crush on Aokiji. I will always love Brook far, far more, but Aokiji is rather cute in this movie, and I love hearing him sing that Marine song.
