Nope. Characters that haven't been developed yet != comedy-based characters. Just like the show, characters are somtimes serious, sometimes not. And it takes fucking time to develop a character.
The writing isn't bad, bad would be Dragonaut. SE is decently written.
Pacing isn't too good, I'll agree with that. But below-average pacing does not make a show with great art, animation and music 'mediocre'.
