I know that Season Four is only half way over so I can't say this about the entire Season but who else agrees with me that Season Four is the best Season to date?
It's been quite good, but unless we see a new character as memorable as Chrysalis and Discord, it won't be able to top Season Two.
Where it's at right now, I feel it's right on par with season 2. Like Ridley touched upon, something like a bold and memorable new villain would shoot se04 up to being the best season so far, at least for me. Not sure whether that'll happen, though...to be honest, I really want there to be a recurring villain whom the Mane 6 face off against at least twice per season, as opposed to one-shot villains like Chrysalis and Sombra who are featured in one episode, swiftly defeated and never to be heard from again.
She didn't technically exist, though. She was just an illusion created by an enchanted comic. Also, that episode wasn't very good.
This season started great but up to about episode 10, It's kinda gone downhill for me. Not dreadful but just, not as entertaining. I hope it picks up again and then I might consider it a Season 2 beater.
