If everyone really did love Attitude Era then why did Wrestlemania's of Attitude Era had so low buy-rates?

Because people watch wrestling for the entertainment of the storylines, and since wrestlemania was about wrestling and not many promos, the buy rates where low, but today the attitude era fans complain about todays lack of good promos, but at wrestlemania, since todays erais more about making good matches, the buy rates are high for wrestlemania, because there lots of great wrestling for people who want to watch a good match. another reason is that on house shows in the attitude era, like RAW & Smackdown, they ddnt put on great matches, as it was all about promos, so people naturally assumed that wrestlemania would have poor quality matches. but in todays era on house shows there are alot of good matches put on so people assume if there are good matches of house shows, naturally there must be better matches on wrestlemania, hence the better buy rates. i dont know why people hate on the PG era, the storylines are less entertaining i agree, but thats because today it more about rivalry, and in the attitude era its more of a R-Rated Drama.
