I understand that some of you liked him in the New Class and some of you don't. But some of you don't understand why he came to the New Class.
The reason why is because that his role as Screech in the original class wasn't popular to his own level. IN the original class, his role was popular to the people under his level. IN the new class, he started okay in seasons 2 and 3 of the new class, but starting in season 4, he was reduced to a virtual cartoon character. The New Class may not be as popular as the original, but Dustin did a better job in the new class than in the original class and his role was popular in the new class.
