100% agreed on smoothies -- one of the few true missteps. As a minigame of mixing ingredients, it was fine, but I struggled to get solid use out of the effects. (And also shattered Hyrule's economy via mango smoothies, but shh. xD )

Interesting; I had exactly the opposite experience (loved Gerudo, found the Zora plotline tedious/repetitive/predictable). As nice as it was to see both Zora types together, I felt like neither of them were quite done justice writing-wise.
