7. Best Night Ever - Amazing episode of season 1, the most memorable one, but it didnt feel like a finale to me so...
6. Twilight Kingdom - A bombastic finale that made you proud to be a brony, even myself, but time went on, the novelty has been worn off. Celestia's plan is dumb. The other mane 5 are useless, they just there to remind us the past key episodes and triggers of Rainbow Power, only Twilight actually do something worth-watching, that is what make this finale so low in my list. Whenever i rewatch this finale, i always skip to some funny parts and the fight scenes.
5. Magical Mystery Cure - This finale should be two-parters, i blamed Hasbro for this, but for what it was, i enjoyed it. The songs are amazing, they wont get out of my head anytime soon. Some people call Twilight's descent a 'jumping the shark' moment, to me, it's proved to be capable of changing status quo which a lot of cartoons dont, this finale made me take this kids show more seriously.
4. Cutie Remark - The most grimdark finale with multiple bad alternative universe, it's reallly interesting to see 'what if' scenerios where the mane 6 fail to save the world. Starlight's reformation is believable enough to me, she gave up on her own and never begging for forgiveness, she ready to be punished (some people just ignore that points in their complains about Starlight face-heel turn), it's Twilight decision to forgive her as a Princess of Friendship. I didnt like the backstory that much, i thought it was a weak motivation for a villain, but after many Starlight episodes thoughout S6 and S7, i finally have a clearer picture of Starlight's psyche. So, the backstory is fine, i dont mind it anymore. The reason i cant place this finale higher because of the BS song sequence, they should delete that song and let Glimmer has that last few minutes to make apology speech to Equal ponies.
3. Shadow Plays - Amazing lore-building finale, it tied to Tree of Harmony origin so well, i like it. Starwirl is a jerk but S3 confirmed that dude sucks at friendship, make totally sense. All mane 6 members actually contribute to the cause by their own strengths and wits (finding the artifact), they use their ability fit their elements of their ancestor. Starlight is great in this episode, she realized the bigger problems and suggested a better solution, mind you, the shadow will be defeated no matter what, Starlight is just there to give a better ending. I feel bad for her in this ep, Sunburst sided with Twilight & Starwirl, ignored Starlight, i want to punch him in the face right now, this finale and Uncommon Bond is a nice combination... They dont waste any precious screentime, i really appreciate that, nothing feel like filler. Twilight is too fond of her idol that cloud her judgement, which is understandable, because it happened in Twilight Kingdom and being addressed in A Royal Problem, she cannot think straight when her idols are around. The shadow has super cool concept but he didnt do anything interesting in the final, just a practice target for Element of Harmony. Stygian's backstory is great but i have a question, why didnt he try to explain whatever he doing instead just running away? Sirens are a big bonus to this finale.
2. To Where and Back Again - An unique finale with combination of secondary characters had to work together to defeat the evil queen without magics, the concept itself is already a bit tricky to write because the Mane 6 are usually the main characters in two-parters and how did they pull out? Well, it went beyond my expectations, i didnt expect it to be that great. The build-ups are subtle that you couldnt even predict what they are going to do with the finale, Trixie become friend with Starlight in No Second prance then become hero of Equestria, a reformed changeling become King of changeling, Discord interact with Trixie and Starlight herself become an enemy with Chrysalis, how could you see this coming? Every members of the group contribute to the story, their dynamics are far better than mane 6 in their recently finale (Twilight Kingdom is just about Twilight, Remark is just about Twilight), each other shine without foreshadowing each other, Starlight couldnt save the world on her own, its the effort of the team make it work. There are some clever moments that surprised me like Thorax disguised as Starlight, Discord being tricked by multiple Fluttershy, Chrysalis snapped her neck. It not a perfect finale for sure, the Act 1 is slow, the changeling's actings are too obvious, how Chrysalis captured everyone were left unknown (even they are explainable but still...), changeling new designs hurts my eyes, i am not seeking for perfection of literature, i am seeking for entertainment and this ep delivered, the entertaining interactions between characters make this finale work. The reason this finale is higher than Shadow Plays is Chrysalis's 'FUCK YOU' to Starlight's reform speech.
1. Canterlot Wedding - Another unique finale featured Chrysalis. This is a slice of life about the royal wedding turned out to be a Canterlot Invasion, this is best plot twist of the entire series, no one see it coming, its not a Best Night Ever, nothing in the show can top this plot twist. This Day Aria is the best mlp villain song ever, nothing in the show right now can beat this classic. Chrysalis is easily become fan favorite villain, she is just entertaining to watch, her plans are actually smart beside trapping Twilight and Cadence in the SAME DUNGEON , everything is ruined because of Deus Ex Machina which is very common in early two-parters of the show... I like Cadence and Shining Armor, they are nice additions to the show (and the abomination Flurry Heart came later on). The scene mane 6 beat the shit out of those changelings is awesome, it's so cartoony violent and funny, it's so 'Powerpuff girl', the mane 6 can defend themself when the situation called for it. Twilight is annoying but i dont mind the old Twilight, i like how she is so obsessive of her brother. The moral is meh (trust your instinct) but the show used to add moral for the sake of it so i dont mind. There are some bad writtings that you may not like if you prefer the writing of later season (the villain is dumb in the end, Cadance and Shining Armor came from nowhere, the main character is annoying) but this finale is just... fun to watch, the songs are amazing, the mysterious atmosphere is great, the plot twist is amazing, the humors are good, the actions are awesome and totally memorable, that all you could ask for a good finale.
(Editted) None of them are in my bad category, i enjoyed all of them, just some of them better than others.
