- The remixed intro theme doesn't sound very elegant to me. The voice glitching a bit 'hacky'. Although it seemed to be heavily inspired by brony music. Same with the nice intro animations. A lot of abstract playing with shapes and colors.
- When Celestia mentioned that Sunset Shimmer might bring harm to the other world using the crown, one of the elements of harmony, I was amused by the pun... HARMony.
- Spike following Twilight was pretty reckless considering what Celestia expressed a moment before.
- Fluttershy's encounter with Twily and Spike is clearly a redo of the original one, but it seemed too mixed regarding Fluttershy's shyness level. First she's moderately shy, then totally, then back to moderate.
- Trixie could at least have tried to cover up the inserting of the coin into the vending machine. She's purely imagining, not even trying to put on a show. Extremely lame, haha.
- Getting the crown ... first extremely complex, then boiling down to ridicuously simple measures deciding the result. But that's not uncommon in the movie world, and I'm not saying it's diappointing, just that it's a bit old.
- At roughly 1h1m25s they decided to cram a Wilhelm scream into the movie that totally didn't fit the teenage crowd there. Hommages should be done with respect.
- Sunset shimmer called it a high school, although the school's name says it's a college (if I'm not mistaken. It might be that the college was actually a slipup.). I can only assume it was meant in a demeaning way, but that would be quie a lame way. Otherwise it was a slipup in the script. Is she really that pathetic that she tries to insult a college by calling it a high school?
Generally, only few details bugged me in the beginning and it got better and better over time, and if you've watched that one extract with the mensa musical on Youtube, you're missing all the context. It's much more powerful when part of the whole plot. I was almost moved to tears by it.
This movie is an invaluable influence for people of all type. It successfully conveys and lovingly celebrates the original message of MLPFIM.
This humanized version also helps to make it even clearer that you can find people like the mane 6 in this world, too. This seems to be kinda unrealized when I hear people equaling Equestria to a land of eternal bliss or something... because it's obviously not. They have many of the same mundane problems that we have.
The writing, especially the dialogue writing, is done very well. All characters act and react quite naturally and believable to events around them, and with that I mean based on the circumstances of the MLPFIM universe. After all, it's still supposed to be wacky, fun and magical. ... Well, OK, maybe with one exception where there was a somewhat forced misunderstanding, but it's nothing that couldn't happen in real life, too.
I'd almost say this is a quality of writing I'd love to see in the show, because it's at least a tiny bit above that.
P.S.: My impession becomes clearer and clearer that Pinkie Pie wields very powerful but subtle magic. Or is wielded by it, haha. Her character carries a profound message, almost an ambassador of what laughing and not taking life too serious can accomplish. In short: I just love her more and more!
P.P.S.: Here's my favorite screen from the whole movie. Not really a strong spoiler, but a moderate one, and maybe you want to see the beauty in context, too:
