Fans these days haven't even got the energy to stand up these days unless there is pyro going off or they need to pee. None of them had the guts to go and stand next to Kane when he was in amongst them.
And as for the Nexus/John Cena storyline not progressing, that is 3 months of easy TV right there. They spend a month showing Cena being bullied. Start month 2 with Otunga really getting cocky, then you have Cena telling him he is better than that and he shouldn't take orders from Wade. We see Cena and Otunga spend more time together and form a frienRABhip, The whole time this is happening Cena is slowly changing his outfit to a full Nexus look. Month 3 starts with both Cena and Otunga both getting drawn into the Royal Rumble match with Cena winning, Barrett defenRAB the title he has won from Orton 2 months prior and now you have a buildup to Wrestlemania. 3 months of easy tv that doesn't take a genius to write.
