What it effectively did was transform the audience into zombies, putting the glasses on and off. People were confused as to when to put them on or off. The audience was so distracted by the 3D glasses that they forgot to watch the band and get into the show like they did on the Reunion tour. What a waste. When you continually pump stuff and then don't deliver, it leaves a sour taste in your mouth.
Gene always talk about giving the fans what they want.
They have lost touch with whom they think their fans are. For example, fans want a change in the setlist. Gene's response has always been that those fans are not representative of the majority, and you can't please everyone. He feels the need to play it safe musically onstage, despite his wild demonic persona, spitting blood and fire and all, talking trash to interviewers etc. That goes for Paul too.
