Power metal is awesome. It's probably one of my favorite subgenres of metal (right behind prog metal, I'd say). However, it has to be along that thin line of being all classically influenced, but not hilariously cheesy. Dragonforce crossed the line, as did Rhapsody and Manowar. Blind Guardian is really toeing the line on a lot of their songs, but I like them. Nightwish is the same way (I wonder who they're going to get to replace Tarja. I personally hope it's someone who completely doesn't try to imitate her). Iced Earth is well back from the line, more towards straight metal, but I like them, too. I could go on, but this seems to have already been gone over in the thread's first life.
