To you it is, but for me and many others, it is not. People have different tastes.

I am still enjoying Season 4 even today cause of all of the things they have done lately (Happy Birthday Isabella for example), and it never felt stale at all in my opinion.

We won't know until Dan and Swampy reveal what they have planed plus I doubt that they will send them to school cause they said time ad time again that they will not do that.
