Too many people like boring, pretentious sounding music. That's what the problem is.
I've also been subjected to the Maccabees and Two Door Cinema Club in recent times, and a friend wanted me to go with them to Berlin to see The XX. At least the Arctic Monkeys actually have some good songs which are distinguishable from one another, rather than sounding like the produce of some drugged up depressed photography student.
I mean, at the moment you'd still go to an Arctic Monkeys gig to dance and have fun, rather than to contemplate slitting your wrists, but they're heading dangerously in the wrong direction, imo.
Maybe if he jumped around on stage a bit more and had his drummer join him in escalating anthemic chants of "ohhhhh... Ahhhhhhhhh.... Heeyyyy" a la kaiser chiefs they'd be more fun?
