I mean I haven't seen that feat, since there are only fractions posted which are also apparently out private. But yeah, that feat is incredible and makes you wonder what point there is to even have a DF, if you keep up with a literal light man on terms of speed, with your Haki being able to shut down DF.
But is this film really non canon? Oda supervised the film and made Uta basically canon. I mean, sure, it's not canon in terms of fitting into the story of the Manga, but I'm sure the abilities portrayed in the movie lie within the user's capabilities.
Though then again, Luffy was beating Shiki pre TS and Douglas Bullet pre advanced Haoshoku (and internal destruction?). I mean I'm honest, I haven't watched a single one piece movie apart from YouTube scenes, lmao.
