Honestly, I really wanted to like Discord a lot and to regard him as one of my favorite MLP characters, I really did. But the way the writers portrayed him and made him do stupid actions and decisions all the time (like you said yourself) has really dimmed my perception of him overall. I really dig his relationship with Fluttershy, Big Mac, and Spike, but other than that he's been unnecessarily rude to the other characters. I wouldn't mind if it were sometimes, since being snarky seems to be part of his personality, but doing it all the time is just overkill.
Well, I can't deny that Discord spends much of his time being a jerk. No beating around the bush there!
I actually used to dislike him quite a bit, but after Season 4 he somehow began growing on me. I realize he's not everyone's cup of tea, though. The way his personality demands attention both from the other characters and from the viewer every time he shows up probably contributes to how fans are divided between loving and hating him...not a lot of neutral ground. I was disappointed that certain episodes involving him (What About Discord, Matter of Principals, the show finale) did not fit with the character arc they'd been giving him earlier at all. I wish the fan theory that he'd actually been trying to trick the villains into
reforming when he released them would've been correct--that would've been far, far better development for him.
Did I mention that when director Jim Miller was interviewed on the season finale, he said that having Discord be Grogar made sense considering Discord's weird logic, then went on to say Discord was his favorite character?? Just--
gahh--what--
WHY would you give your favorite character such a poor ending at the finale of the show? How could you twist his development for the sake of some "big reveal" that, no matter what you may have thought, DOESN'T make sense??
You betrayed me and the rest of your fellow Discord fans, man!!*Sigh*...Nevertheless, though I can sit here and go on about all this, I've never been able to bring myself to quit liking Discord again. Who am I kidding here? I get a kick out of wordplay and visual gags, and this guy delivers them in buckets. More than that, his unlikely friendships with Fluttershy and the guys always make me love him again regardless of how much he's screwed things up. Call it Fluttershy syndrome!
