I'm a great Bon Jovi fan. I've seen them live twice and own almost all of their albums. They are without a doubt one of the world's premier stadia rock bands, up there with the best: Van Halen, Aerosmith, ACDC...
That being said, however, when they diverge from their trademark sound, they often come across as a mediocre, even below average, generic soft-rock group.
Clearly, Jon and Richie would dream of being considered alongside the likes of Springsteen, Jagger/Richards or Dylan. Unfortunately, they just can't pull it off.
They and their songs don't hold up those of their rolemodels. Songs like Living on a Prayer and Keep the Faith are great rock songs, but lack the lyrical content and emotion to work accoustically. Hearing John and Richie sings about how life's tough for Jeena or how he wants to be a cowboy just doesn't work when you see them playing guitars on stage that are worth -literally- tens of thousands of dollars.
Bon Jovi should stick at what they do best -Rock! And, when they do, there ain't no stopping them!
