Dio's Holy Diver was a lot, lot better IMHO.
I thought the video was pretty lame (i know that's what they were going for, but it wasn't even funny... just bad). As for the song, though, I believe the complete opposite, because I hate pretty much everything ever sung by Dio.
Aye, i thought the song was pretty decent aswell.
