I don't hate the later seasons, and actually enjoy plenty of episodes from them. But to be honest, I probably would've preferred the direction of the show if Faust and more of the older writers had stayed. I prefer the writing style of the older seasons, and think the show would've ended off better if it hadn't run for so long. Equestria Girls would've never existed, along with some fan-pandering stuff, which I consider to be a good thing. Twilight probably would've stayed a unicorn and her tree library wouldn't have gotten destroyed in place of an ugly looking castle too, both of which would be a plus for me.
