So basically Apht understands why we like it, just not why it's overhyped.
The line theory.
The like one has for a show can be represented by a line that can be drawn between their expectations from the show and how well it impressed them. Obviously because ponies everybody thought it would be this stereotypical girly mass of heaping ass. It was the complete opposite though, the far other side of the graph, effectively positively shading the entire graph showing a very high like and interest.
