In all honesty, I don't watch many music videos. I never really have. The bulk of the videos for songs I listen to mostly involve the group in question dancing/singing/playing instruments, and not much else. It's such a shame because a lot of the time it's just wasted potential. There are so many possibilities but nobody seems to seize these obvious opportunities.
However, here we have music videos/MVs/PVs or whatever you want to call them, that have some sort of story to them, or at least a development of the ideas and motifs used. For this simple trait, they are all flippin' epic.
(By the way, the picture above is the best part of the Monster MV :D)
