The storyline is still in effect, but it's kind of lost it's sizzle IMO. I was actually pumped for the eventual Big Show/Triple H showdown but now, not so much. It made sense for Show to try and run through Orton first as a way of building more anticipation for his feud with HHH, but it's actually had the opposite effect where the stuff with Orton has sort of made me not care as much about an upcoming match with HHH because it seems Show's main anger is now entirely focused on Orton (especially now that he's been put out with the Punt Kick... if it had been Triple H slamming a sledgehammer onto Show's head or something, it would have been different.)
Plus, Steph doesn't even shoot down the idea of John Cena being face of the company. She even states that "unlike my dad, I don't want you to spontaneously combust" even though her dad is the one returning as a babyface to finally take out her and Triple H for good (and possible handpicking Cena as the one to do it at Mania.)
The angle also began with Daniel Bryan being screwed at Summerslam. That's when Triple H and Stephanie became The Authority (although the name itself only came later) and for me, it has to come full circle in some way. But I fear that Bryan might not even have a big role in putting the Authority to rest come Wrestlemania. I hope I'm wrong and if the recent interview that HHH gave on wwe.com is any indication (where he mentioned that he wasn't behind Bryan or Punk's attacks, which was good since he was at least acknowledging them), then I am.
