While the final confrontation and the backstory of Tesoro managed to reach that high canon standard, sadly, almost anything else in here is guaranteed you'll never caught Oda slacking and putting any into his main storyline.
The Western influence of the mafias and heist movies is so apparent and so cheaply recreated, they didn't even try to masks all the twist and cliches they've borrowed. The spirit of the main crew is lost in this mixture, they're even betraying the character in one scene where there are kids being abused and Luffy just standing there watching!
This feels like someone trying to do One Piece instead of really doing it. It's a jumble of everything that you has ever liked about the series, but so try-hard and half-assed, resulting in zero personality.
