Fine, I'll bite.
I have yet to see 360, but I know I'll love it. It's going to be one of the highlights of the year for me, I'm sure.
Pros? It's a fucking U2 concert! Seeing my favourite band play my favourite songs rocks! It's a treat for me to see them live, and I'm not one to bitch about the setlist or the stage setup or whatever. I'm happy with whatever they choose to play, and they always have cool looking sets.
Cons? Well, the only cons I've ever experienced were assholes sitting near me who dumped beer on me, or were blowing cigarette smoke into my face. Those distracted me from the music, and dampened my mood a little bit, but I got over it pretty quickly.
Sorry if this makes me seem all fangirly and dumb, but I love live music, and it's extremely hard for me to find cons in the concerts I've been to.
