I've been kinda on/off with Bon Jovi over the years. Two albums ago, I hated the man and his band on their attempt to essentially come back from the dead. However, their more recent work has been fairly decent (I did like Who Says You Can't Go Home?). I'd agree that Slippery When Wet is not only their best album, but probably one of the best of the 1980s.
...I dunno. There are days where I like them and there are days when I don't. I'm better off with the other hair-metal bands of the era, they tend to match my musical tastes a bit better, however Livin' On A Prayer will always be one of those songs you just have to crank-up, no matter how much you may or may not like the band...
