Exactly my thoughts and definitely one of the reasons why they aren't such a good live (!) - band like everyone says. The interaction with the crowd is besides the quality of the performance the most important factor in a live show and for some reason, Chester and Mike can't say more than "You guys are cool", "This is our last song" and "Put your hands up" every single show.
I don't know what happened after 2007, but since the release of Minutes To Midnight the crowd interaction became less and less which is really sad. I miss the spontaneous and funny speeches to entertain the crowd. Just rushing through a set, makes a show boring which happened here
