I can definitely agree with you there. I really would have liked it if the kakamora got some more time, or if we spent some more time in monster land. (I forgot what its called)
Well that was just for the one song, so I think its fine. It meant to stick out. They even played with it a bit where Maui gives Moana cartoon stuff, but when we come back to the real world, its actually a bunch of rocks, shells, and seaweed. Though this does raise a few questions. Like, is Maui able to induce druggy hallucinations with the power of song?
Again, it was just for the one part of the one song, but seeing as its not as significant, and still takes place in the same plain of reality, I can see where you're coming from. Also, that's another thing that need more time. I really did like Tamatoa's character, but he really didn't get enough attention. He's played up as Maui's great rival, but all we get from him is a few lines, a reason for Maui not to have his hook, and a pretty good song. Also, as a bit of a side note, did anyone else notice when Maui and Moana leave, Tamatoa says "Did you like the song?" I don't know about you, but I really liked that.
Well that was probably intentional, seeing as the entire scene was a reference to it.
