A nostalgic Filler about Luffy's feelings and his past. Luffy acknowledges his feelings for his crew.
Luffy takes a leap of faith and jumps into the waterfall determined to protect his crew till his last breath. Nostalgia runs through you when you see Shanks suddenly pop into the screen. It is a leave-able filler but better watched as Luffy's past is refreshed about 270 episodes in the series.
The old animation doesn't seem to be remastered as it is in 4:3 Letterbox ratio, but still good and smooth animation, Story and Script are good, music is great as always.
Overall a good Filler!
