I'm smiling, but something's not right here.
So here we have the second Pinkie Pie episode this season, and her most cartoonish appearance to date. She sings more than in any other episode, reality couldn't get much more broken without Discord around, and the energy never drops! All of which bugs the hell out of Cranky Doodle Donkey, a curmudgeon moving into Ponyville with isolation on his mind.
Pinkie tries to make friends with Cranky in varying degrees of obsessiveness, energy, and common sense, but Cranky remains unmoved. When Pinkie's antics destroy one of Cranky's prized possessions, he tells her off for good. Or it would be for good if it were anypony but Pinkie Pie, who rallies once more and melts Cranky's icy heart by reuniting him with a long-lost love.
This episode gave me every reason to love it: there's a fleshed-out awesome song and several smaller ones, it stars Pinkie Pie, the animation is exemplary and the gags are hilarious. So why am I not enthralled by such a display? Well, it all comes down to story.
Throughout the episode, Cranky is sympathetic; he's not really doing anything wrong by ignoring Pinkie, and his treatment at her hands gets pretty rough and embarrassing. I find it difficult to root for Pinkie's efforts when it's clear they end up worsening the relationship. Sure she has good intentions, but she still doesn't take Cranky's feelings into much consideration.
She does do a few things right, like getting him a new toupee or finding his lost love. Which is actually the other problem I had with the story; Matilda, another donkey who turns out to be Cranky's Shallow Love Interest
from X-ty years ago. There's not even foreshadowing on her being the lost love; Pinkie Pie only figures it out from her creepily thorough knowledge of everypony in Ponyville. Oh, and if Cranky searched Equestria for her after they met in Canterlot, how was Ponyville not the first place he looked?
I found my opinion on this episode to be similar to that of "The Last Roundup", an episode that had a few plot problems but had a lot of cartoon flair to the point where I could overlook the holes. This episode was even more cartoonish, but the problems have swelled accordingly and I can't let these go. It's a shame too, because I really liked "The Last Roundup" even disregarding Derpy. This episode put a smile on my face, but it was only skin deep.
