You have to consider the context of the genre. The entire genre is crazy gay and of that over produced california soft metal Poison has the absolutely gayest songs. And of those songs, Every Rose is the gayest. Those guys in Poison, I like to believe that they knew the score and that is why Every Rose even exists. They wrote the cheesiest, sappiest, most banal rock ballad they possibly could. And they NAILED it.
Those guys in Motley Crue... they really didn't know the score. They still don't know the score. But they're rich so they don't have to. I dunno what kind of drugs they were into but... organic brain damage.
Its all moderately shitty echoes of glam rock. Now K.I.S.S. or Bowie or Queen -- that's some glam rock I can get behind. Crue is a pale shadow. Shit, even Winger actually had a decent song or two for being a hair band.
Edit: Basically I don't think you can write something as bad as Every Rose on accident, where I do believe you could write every Crue song there is on accident. I think that Poison even had a pedo song of their own, but I'm not going to youtube digging for Poison songs! The NSA is watching, man.
