The Book of Souls is Maiden just trying to be too much and they fall short. I think it in a way resembles Dream Theater's " The Astonishing", in the sense that it sounds good while you listen to it. But it's messy, and just pieces of it leave any lasting imprint. Don't get me started on The Empire of the Clouds.Dance of Death and The Book of Souls are both awesome.
I only regularly revisit If Eterenity Should Fail and the title track. I can do fine without the rest.
I love Monty Python in general and John Cleese in particular.Nice Fawlty Towers reference!
