I'm not surprised. This was the first PPV this year I didn't buy, and I don't think I'm alone.
Other than the main event, the rest of the matches felt like filler matches, either to pad out championship reigns or to draw out feuds.
Basically, if the main event held no interest for you (and for a lot of people, it didn't), there was no reason to invest money in this one. I'm not even interested enough to stream or torrent it.
