One piece possibly has the best anime fillers. The best part about them is, they do not create plot holes and there are no year long fillers like Naruto. There are a minimal number of fillers and good ones. This one was good but all of the same was pretty uninteresting except Luffy vs. Law fight and superior animation.
Breed who manages to put a collar on Chopper, Luffy and Law controls them and orders Luffy and Law to kill each other. Breed reveals his plan and Caeser's requirement for it.
Only good thing about this was to see Luffy and Law fighting each other, it would have been good to see a full throttle fight, but this was good too as I don't see them fight each other in the near future in canon. It seems that to convey his orders, Breed's voice is to be heard by the subject, as he uses a speaker to convey his order to Caeser. Breed as a character is hollow.
Direction/Animation: Good.
Script/Screenplay: Weak.
Music: Nice.
Overall a watchable filler with good animation. Good news being, canon starts in two weeks time.
