Good album, but not a great album. Long songs are great when done well, but can also be boring if there isn't enough in them to grab you, and after a few listens, there still isn't anything that grabbed me on this one.
IMO this isn't as good as BNW or DOD, and if you're looking for a great new album with Bruce Dickinson's vocals but can only afford one, I'd say buy his solo album from last year (Tyranny of Souls) instead of this one.
I got 3 albums around the same time: A Matter of Life or Death, Motorhead's "Kiss of Death", and Rhino Bucket's "And Then It Got Ugly". Figuring I'd be listening to Iron Maiden the most, I put it in the #1 position in my car, and to be honest, I look forward to it being over so I can get to these other albums, which so far I've liked better.
Again, I'm not saying this is a bad album (I don't think Iron Maiden has ever put out a bad album), and while I wasn't expecting Number of the Beast Part 2, I think I was expecting more than this and didn't get it.
