Well since no one's mentioned it yet, I'll give you my opinions of the movie ***Spoiler FREE***. The animation wasn't great (it lacked the same feeling and the characters seemed to have no emotion), and the story was badly laid out. We don't even find out about the motivation for the main antagonist until near the end...like it was an afterthought or something (and it was a stupid motivation to boot - and I thought Starlight Glimmer's motivation for enslaving the village was bad). The characters just weren't believable as they never prescribed any real motivations behind their actions. Overall it was a very shallow film, not worthy of the MLP name.
But honestly, this is like pretty much ALL movies I've seen in recent years. Characters just have sex for no reason (I'm talking about OTHER movies right now, NOT the MLP movie!) when they don't even know each other, they throw some transgender or lesbian/gay person in for no real reason, and the directors don't do anything to make you actually CARE or even give two shits about the characters. There's no CONNECTION there, and that's what was missing with the MLP movie too. If I hadn't known the mane6 from the TV series and this was my first exposure to MLP, I probably never would have become a brony because they did nothing to connect me to the characters. Which is fine I guess for the mane6 because we already know them, but I couldn't care less about any of the other characters. I can't even remember their names. I only remember Tempest because she looked badass in the movie trailers and I thought I'd really like her character, but like all the new characters they didn't do anything to make me actually CARE about her.
The bar has been set pretty darned LOW in movies in the past few years. It seems all you have to do to make a fortune nowadays is make a bunch of explosions and push the latest PC bullshit and people eat it up like mindless sheep. I miss GOOD stories, with BELIEVABLE characters that they actually made you CARE about. Not the crap I've seen lately (the new Star Wars movie, the Abrams BS "Star Trek" movies, Fantastic Beasts and Where to Find Them (I think it had something to do with Harry Potter but the film was so bad I don't remember anything about it), and now this steaming pile of a MLP movie. I've seen a few other movies in theaters, but they were so bad I can't even remember their names. I'd seriously rather watch one of those weird black and white movies from the 1930's than another one of those steaming piles. Granted, the MLP movie is the best movie I've seen in a long time, but that's not saying much.
In conclusion, I give it a 4/10. And that's because I'm biased and love ponies so much. If it hadn't been about ponies it would be a 1/10 or 2/10 because they did absolutely NOTHING to make you care about ANY of the characters.
