I guess this could be considered a review, but this is honestly gonna be more fanboying then reviewing since I didn't find anything majorly wrong with the episode. All right fanboying in 3.2.1
THAT WAS SO AWESOME, I MEAN REALLY. Now that that's over time to explain why Pinkie Pride is the best episode of season 4
1. Pinkie Pie's characterization: Throughout season 4, Pinkie hasn't really done much outside of being a gag character with a few exceptions like Pinkie Apple Pie. In this episode, she was characterized perfectly. She actually had depth outside of being a gag character. She also had some great development and got her key (seriously a rubber chicken is so fitting for her).
2. Cheese Sandwich: Weird Al did an excellent performance a party pony who steals Pinkie's spotlight.
The episode didn't go the easy route and just made him an antagonist but had a great plot twist of him being inspired to throw parties by Pinkie. It was such an excellent plot twist
3: The songs: The songs were excellent. they each flowed well with the episode. It's hard to pick a favorite, they were all so amazing, the song Pinkie sung in the beginning was very reminiscent of the beginning song in Beauty and the Beast, there was a sad song with Pinkie singing about how she's always thrown parties with nice callbacks to earlier episodes kind of like in Magical Mystery Cure that had amazing animation, and the other songs were excellent. Also the live action sequence with Gummy and Boneless was amazing and reminded me of an early Spongebob episode.
So yeah new favorite episode in season 4, new favorite Pinkie Pie episode, and one of my favorite episodes in season 4, I'm giving this episode a 10/10, no that's not enough, how about an 11/10, nah still not enough to how awesome it is, I know,
Final score: 12/10
