Mainly that it doesn't seem to have the same polish as the earlier ones.

Ponies acting out of character or forgetting stuff they learned in previous seasons (apparently Trixie is now a total c*nt for no reason, the Royal Sisters apparently having zero respect for each other's duties), entire episodes relying on on tired cliches (the three guys who were supposed to help Fluttershy all but sabotaging her), that sort of things. Bascically not putting in the extra work to elevate the show from being "just" a kids' show to something better.



I also still absolutely despise everything including Stalight Glimmer, but I do realize that I'm pretty biased in that matter.



All that being said, there are some parts I do like, like them actually moving the stuff forward in little ways. Dash actually becoming a full-fledged Wonderbolt and Fluttershy opening her sactuary, which felt like a really natural goal for her to have, Sweetie Belle realizing that she's growing up. It's nice to not have everything stuck in an eternal status quo.
