Do you think Thriller Bark is the weakest arc pre-Timeskip?

Don't get me wrong, I like Moria and his ability and theme.

The beginning felt strong until it turned into the usual shonen good guy vs bad guy plot. It wasn't as heavyweight as Arabasta or (obviously) CP9 arc. Skypiea, too, seems a more wonderful arc.

Thriller Bark seems to mainly introduce Moria as the Shichibukai and hint the upcoming war (with the arrival of Kuma). And even the fights are forgettable (except Zorro).

Yes, there is Brook.

And that's it...?
