You get met with a few inconsistencies (as per usual) for the canon. The ones that I noticed include them saying they came there to find the treasure. You can't just head to islands unless you get an eternal pose, so saying they came there for the treasure doesn't make any sense. They did this in the third movie as well, they even had a map in that one lol.
Also, at one point when they are first talking about it I believe Nami says that the Cursed Holy Sword, or Sacred Sword? is the greatest treasure of the Grand Line... I thought that was the One Piece? lol
One other would be when they are discussing Saga's backstory, how after the explosion he miraculously survived but his arm wasn't usable, so he "wandered into the grand line to this island" like, how? That must have been pretty hard right? Idk I guess at this point the Grand Line isn't as hard to get to as we thought at first.
Some things I loved though where the fight between Sanji & Zoro, like damn that was intense!
And the bit with Luffy & Usopp in the caves.
Also when Sanji is fighting one of the goons and he goes. "My steel armor can't be borrken by your foot" and Sanji kicks him on top of the head and says "Then maybe your head and your face need armor too" That was great XD
The fact that this movie seemed to be centered around Zoro, with him even beating the antogonist, but still not having as much screen time as the others I thought was interesting.
Also we did see more of his backstory though! If it's canon anyways?
I enjoyed more than I think I should have if that makes sense. Definitely a fun movie all in all.
