Well, to be honest... Its not really me :S
Not that its bad, just not me.
The animation is really good! (even better if you compare it to many of the things out there now a-day)
The lip sync is better than many, but I find the voices acting to be on the annoying side (to many high pitched notices and repetitive sentences)
The "Story" of each (only saw Return to Harmony 1 and 2 and Hurricane flutter-shy) is fine, sweet and creative, but also relay predictable after a few minutes in (I like surprises)
The overall ideas for each episode (Read more of them on Wiki) seem to be done over and over by other movies and series, with exception of the setting. but then again, it can be hard to make anything new now a-day..
In short(okay, I failed there), fine and good, but a bit overrated if you ask me... and that probably is exactly why its not in my taste, I tend to like things better if they are not "pepped up" to be much more than they are. that, and the fact that the theme and style does not speak to me, don't get me wrong, I like "sweet" and I also like the "soft drawing style" (I have no idea what it's called) but if you combine it like they do in MLP, it just gets a little bit to much for me.
I can see what appeals to so many, and have no idea why it also get's so much hate some places, (but I guess a combination of hardcore haters, trolls and people who don't even want to see it before judging it)
So.. did I learn new things about MLP.. Yes, a lot... was I converted into the Bronies fold and stable? not so much.
Thanks for the effort of finding them and answering all the questions Burns, it is fascinating, but for me more as a "know about that culture" than "join that culture"
