I just ended up watching the first two episodes of MLP:FiM, and I have to say... Hmm.
I thought the entire way the ponies interacted with each other in the first episode was really coercive. That's not necessarily a bad
thing, per se; I did think that the show was allowing us to identify with Twilight Sparkle's frustration at being dragged into things. But I couldn't identify with her, because she's just as coercive to the other ponies - when she did stick up for herself, she didn't say "NO I WON'T DO WHAT YOU WANT", she said "NO, YOU DO WHAT I WANT" instead. And Fluttershy's whole "be as condescending as possible to the baby dragon" thing was kind of jarring.
Either way, though, she was actively rejecting their advances. And how was that situation resolved? It was resolved when they succeeded
in dragging her into something. And then she "realized" that it had been the right idea all along. I think it's very reasonable to say that the events there teach two really yucky lessons: first, the lesson (from Twilight's perspective) that people whose actions bother you are Really Your Friends and you should join them instead of doing what's comfortable for you; second and more importantly, the lesson (from the others' perspective) that it's okay to pressure people into doing activities you think they'll like
Still, there were a lot of things I liked about it. I think it did a good job of making sure all the individual ponies had their own initiative and independence, and balancing that with the way they could accomplish things as a group. And they all have their own personalities and that's okay, rather than there being one true way that you're supposed to behave. Which turns out to actually make the group dynamic fairly healthy - in the second episode, they are working together because each of them genuinely wants to work with the others, even though they're independent enough to function on their own, which is a really important property in a healthy group. So despite my reservations, I think the show portrays a pretty good model of human friendship, certainly compared to a lot of the other popular-media portrayals available.
And I feel like it leaves the viewer a lot of room to decide for zemself what to think.
I was kinda disappointed that the Super Good Adult Authority Figure walked in at the end to validate the friends' triumph instead of having their validation of each other be the most important thing, though. The whole backdrop of a monarchic system where it's supposed to be okay that some people are required to obey the orders of others annoyed me a bit, as did the "white = incorruptible pure pureness, black = cackling megalomaniacal evil" thing between her and Nightmare Moon. I suppose I'd say that the show repeats a lot of the somewhat-yucky tropes from elsewhere in the world, even though it also avoids a bunch of the yuckiest ones.
