If we look at it quantitatively the early seasons did not draw in the crowds. The last half has them pulling in the numbers.The early ones were okay. Went on too long in my opinion. But you can say that about a lot of shows.
Having said that some people stopped watching as it was making fun of the weird behaviors of the girls and guys.
I have some of those idiosyncrasies and I appreciate them making fun of them.
Its very relatable to me.
