My replies in the comments to the video:
It was all going slowly downhill after Lauren Faust left. Perhaps the remaining crew wouldn't stand up to corporate like she did, so we end up with stuff like Shining Armor out of nowhere, and Alicorn Twilight. The world building in the first season was really interesting to me, and satisfied all ages that watched it, finally there was a show adults could watch with children that was actually good. When people say "it's just a kids show, stop being so critical", they have really missed that point. Before MLP gen 4, that was true, but we can't just sit here and pretend it's not possible to just make a show that is appealing to all after it was just accomplished. So now they are just degrading into a vapid children's show, and I don't think Hasbro really cares, they just want to continue selling toys in the pink isle.
If any bronies are looking for something else to latch onto that is a community, try furry. They also have the attitude of "I like what I like, and I don't care if anyone approves". You're all furries anyway, that only likes one species. And there is no such thing as canon, you can create whatever you want, even things not furry are accepted, like dragons, dinosaurs, etc. With all the art and animation being created, it can never just die, get cancelled, or be taken in a lame direction like MLP.
