My biggest problem with BNW is probably that it lacks songs i really really love.
DoD has the title-track and Paschendale for example, AMOLAD has The Legacy and For the Greater Good of God and TFF has Starblind and Isle of Avalon to name a few, but BNW doesn't have a song i would rank as high.
The Wicker Man is slightly repetitive and not my type of song (im more in love with the slightly longer Maiden-songs), Ghost of the Navigator and the title-track are my favorites from it, but they aren't near as good as the other tracks i mentioned.
It's actually pretty funny considering that i used to LOVE BNW and held it as one of my favorites, but now it wouldn't make my top 5 Maiden-albums.
