I feel sorry for all the naysayers and people who insist on being negative about Burning Ambition
Imagine getting a chance to see a nice compact expose on a favorite band filled with tons of great footage on the big screen with big sound, kept moving by constant narration from the band, taking you on a rollercoaster of highs to lows and back again, and your main inclination is to shit all over it instead of enjoying the ride and getting hit from all sides with pure Maiden goodness.
So what if much of the footage might be recycled (I personally had never seen any of the Blaze footage, nor had I ever seen any discussion of how the band members reacted to Bruce's departure), or if the band comments were external the production of the movie itself, everything was tied together in a nice digestible package, told a great story, and is a fine enough way to spend a couple of hours with other people in the theater who also love the band.
But I guess that's not good enough for some folks. I hope you don't waste your time always searching for those wasted hours.
