Reasons why Nick ran out of good ideas
1. Criticism and in fears of their shows becoming controversial, they're dumbing them down to death!
2. Not exactly corporate reasons, though I respect and admire LOTR, DC, D&D and Marvel franchises (I don't care if it's like this, like that, it's more like a project when it comes to all of their projects and products)
3. New writers, new social climate and that ironically Teenick is more appropriate for preteens because teenagers don't care about Teenick! They prefer to watch MTV (but does that make me a teenager also, I'm a 15-year-old girl and I watched Heroes, it was better than all of the Teenick shows combined).
