Regardless SmackDown's always been "my" show since I started watching WWE with any sort of regularity, which was around the time of the first brand split. Raw was...Raw...and SmackDown felt like the "rebel" show going against Raw. As a former Nitro fan? That appealed to me.
Plus SmackDown was just the better show during that first brand split. It had Lesnar, Undertaker back before the bottom fell out, Edge, Mysterio, Eddie, Kurt Angle, He Who Must Not Be Named, the Crusierweights (lots of old WCW guys), and most importantly Matt Hardy V1
All helmed by Heyman on the creative end.
Meanwhile Raw had Vince McMahon giving us Kattie Vick and Bischoff handing HHH the old NWA/WCW belt because HHH wanted to bury the whole show play Four Horsemen.
It's really funny how the exact same thing happened this time around. Raw remains the business as usual show while SD is the place where they're allowed to break out of the mould.
An announcer who actually knows and calls moves, the old NXT creative team giving us less convoluted and more straightforward, quality stories. And better talent.
AJ, Dean, The Miz re-inventing himself as possibly the best pure heel in the company, Calisto, Baron Corbin, the Wyatts, rejuvenated Usos, American Alpha, and a more interesting women's division. Also Dolph Ziggler I guess
The biggest problem with SD is the same problem SD had back during the first brand split. The production is too close to the WWE "norm." The WWE feel should be Raw's.
SD needs to truly be something different on the production end to sell the idea of different brands. Give the refs different shirts (something they did back then), try different camera angles. Go back to just a two-man booth. Go with a set that doesn't look like your standard WWE set.
They're doing some of this, but they aren't pushing it enough, in my opinion.
Plus one of the things that made SD unique (Talking Smack) got ported over to Raw (Raw Talk).
WWE should be pushing the two brands apart from a production standpoint. Not homogenizing them.
