The dark match was Bray Wyatt vs. John Cena. It ended with the Wyatt Family interfering for a DQ.
The show was not a sellout. The upper deck above hard camera side was curtained off.
WWE succeeded in turning the crowd against Bray Wyatt. Messing with Jerry Lawler in Tennessee is still effective to draw heat. Other than that, the crowd was deader than dead. Cena and Bryan got the biggest pops. Hardly anything got this crowd excited. Cena even mentioned the crowd wasn't really excited during the dark segment.
Crowd members (not smart marks, dads with their kids) were commenting on how poorly tonight's Raw was written. The crowd did pop for Evolution and the Shield at the end with a This Is Awesome chant.
Hopefully you enjoyed tonight's show more than I did!
