It's not my question, I know why it's a good/bad show. I could say any show is good by copying and pasting your post.
Alright, I'll go into even more detail if that doesn't satisfy you.
The characters have original personalities. Most shows are set up to have a set of characters with the same sort of function as previous shows have done, such as the trio of main character, girl, and nerd. At least 2 shows I've watched have done that (ever watched Nickelodeon?). The characters also have specific personality flaws that makes the show much more interesting instead of having a personality consisting of perfect qualities like a lot of shows do.
The drama is good. None of the episodes have a perfect ending all the time. Season 2's first episode has made it look like all hope is lost, a great cliffhanger. And unlike even more shows, the parties are never always perfect in every way. One of the parties has almost all the characters skip out and temporarily drives one of the characters insane (which is quite funny to watch). The final episode's grand gala party is a complete mess as well.
I can't say there is much action, but this isn't a show about action. If it was a television show based around fighting it would be disappointing, but no, this show is a huge variety. It has no specific "theme" it revolves around, bringing me back to the topic of originality.
The animation is just incredible. The producers have made wonders with Flash, like huge beautiful castles and even 3D effects. I find the animation great.
Alright, I've answered it. This does not apply to every show. Happy now?
