There is some method to the madness. Those matches are a way to have someone new come in, look like a killer, and demonstrate their entire moveset, in badass style. We've also been spoiled, we get all these matches on television so the motivation to buy PPVs is lacking, generally they are rematches from tv. There were days when the PPV match was the 1st match between 2 people in a feud, it made it seem more special.
