Most fans I have spoke with actually say the opposite. This PPV feels more special that the past several years because it is in Pheonix (if you consider it to be a small town, B show worth venue, that is fine. However, people said the same thing about Dallas for Slammi X and look how that turned out) and not anywhere near Florida/East Coast. Second, the BFG series has been excellent this year which adds to the PPV as a whole. Even if you don't like Hardy, the series has made the Aries/Hardy build before ever knowing Hardy was winning. Third, the potential of making key players of A&8s known to the public has a buzz going that involves the PPV. Fourth, the fact that we have had such solid wrestling on a week to week basis means that we can expect everyone to bring their tops to the "Wrestlemania of TNA" (man I hate that comparison). Fifth, the Storm/Roode angle gets it's conclusion (minus the belt) at the PPV and though it has lost a lot of steam, the way Roode cost Storm the belt definately got a LOT of fans attention (most people expected either Storm to win or Roode to interfere in the finals... Not for Storm to lose in the Semi's and let Bully advance).
The hooplah isn't going to be there for BFG like Wrestlemania. It never has, nor will it ever. It's more like the "Starrcade of TNA" in which there will be lots of solid wrestling, conclusions to angles, and the begining of angles. It's not about press coverage, how many stars from old you bring back, or how many times you can get on TV/trend on Twitter about the event. But people commonly compare the two, regardless that they are nothing alike, simply because they only know of WWE and TNA these days.
