I plan on going to the July 22 one at Amway in Orlando, may even go to Battleground which is the Sunday before in Tampa. I went to Raw this past October and had a blast ... except for Sandow losing his MitB cash in attempt to Cena.
Anyways, to me it's all about mindset. If you want to go have a good time, you'll have one no problem. Leave the cynical perspective behind & be as vocal & involved with the event as much as possible, and there's no doubt you'll have a blast. Whenever I go to shows, whether it's WWE, TNA or any other promotion - I always have a blast. Even if the show comes across terrible on TV, live action is great to be a part of & if you're a fan, you should have fun.
Smackdown usually gets a quality dark match after the show featuring top notch guys & they tape Main Event too so you'll more then likely have a great time.
