Their house, their rules. I don't see what the big deal is and why every one pouts so much about having to put out spoilers; click a button and have some respect.
Anyway, I didn't see this show (ye?), but I liked the last two shows that I saw. Their backgrounds have enough entertainment, but the music speaks for itself. I don't go to see pigs flying, spaceships blown up, lasers all over the sky, or video screens all around with cartoons on em. I go to see Maiden play live. Like in a bar, but with 5,000 other fans/friends.
