I have never listened to a Power Metal band that I haven't wholly been able to get into. Yes, Dragonforce suck, but even they have their moments.
My favorite bands include the German School from the '80s (Rage, Running Wild, Stormwarrior, Gamma Ray, Blind Guardian, Helloween, Grave Digger ), followed by stuff like Rhapsody, Firewind, Edguy, Brainstorm, Symphorce, Stratovarius, Iced Earth, Heavenly, Lost Horizon, etc...many more.
However, my favorite sub-genre of PM is Prog Power. Labyrinth, Vision Divine, Symphony X, Angra, Evergrey (yes, they are PM), Adagio (70% Prog, 30% Power) etc.
I really don't know why so many people hate PM here. It is a great genre, and if you look beyond the unoriginal, boring bands, there is a lot of creativity and talent.
