Man, you guys are placing your expectations way too damn high. Can't we just watch the show for a few innocent laughs and ernest moral lessons? I mean sheesh.
Newsflash: No one got into this fandom with high expectations. Most people got here either out of some morbid sense of curiosity, or to get a few ironic laughs at a stupid kid's show.
We are not setting the bar here, the creators did that themselves. And bless them for doing so, but there will be pressure from the fandom to keep aiming that high. You can't hide behind "It is just a kid's show" any more after showing just what they are capable of.
Much like with all the new Super Mario or Zelda games: Franchises that have been incredibly successful in the past, and now everyone is expecting that every new instalment is just as good or even better then the previous one. And once the fans feel something isn't right in the preview, there will be a few cries of
Ruined Forever, because they have an emotional investment in the show, and people tend to act emotionally once something is happening to their beloved franchise. Most of the time, they will be proven mostly wrong, of course, but you can't fault them for being concerned after hearing something that would raise all kinds of red flags if it were any other series.
