While my opinion doesn't affect the show, I will say it anyway. As with almost every show geared towards teens, it could have been a lot better.
The thing that infuriates me most is the characters. Surprisingly Zach annoys me less than what I would have thought, in fact I would say he is the best character and he is only getting better (however, Dylan does get ridiculous story lines like in 'Breakup in Paris'). Cody is frustrating, he whines way too much. Still funny, but a bit extravagant if you ask me. London, while albeit funny as well, her air-headedness is taken to the extreme. She wasn't this bad in the first season of the original Zach and Cody. I also can't stand the way she makes fun of Ms. Tutwiler, her teacher. Erin, who plays Emma Tutwiler is a beautiful woman, and in no way is she ugly! How can her students get off with making fun of her? It shouldn't bother me, but it does.
As for Woody, Kirby, and Marcus – they are unnecessary characters. Zach is already a bit ditzy, and London completely daft. When you put in Woody and Kirby, it is just foolish. They add nothing to the show. We could have had great supporting characters like Esteban (not saying bring him in the show but someone like him). And Marcus, he just popped up out of nowhere and there is nothing special about him.
I like Bailey but I am tired of the excessive talk of home life back in Kettlecorn. She is a less than mediocre replacement of Maddie.
The reason for my high rating is because it is an entertaining show, stupid, but something to laugh at.
