Sorry

I hope it doesn't seemed I was patronizing it wasn't my intention.
About clichè, I meant that you could imagine what will happen next easily, for example I think the exchange/fight between the 2 brothers and Luffy was easily predictable and the same was for the behavior of Sanji with the female enemy.
In more general terms, because this is a filler the authors can't really develop the characters or change anything of important, so even before the arc starts you already know that the Strawhats will fight enemies weaker than them, whom for some twist or because of the setting will get the advantage, but in the end they will be totally owned. For these reasons if the new characters aren't very interesting or the plot hasn't some peculiar elements, then the development of the plot of the filler could be considered predictable, imho.
But you should consider that I like the manga more than the anime.
I hope I made myself a little clearer
