Led Zeppelin Movie

I personally really enjoyed the music performed in the movie we watched this week, however I found the documentary itself extremely boring. The fact alone that it was just continuously showing footage from their shows without any commentary or breaks from the show to actually talk about the band Led Zeppelin. My favorite song by Led Zeppelin has been Stairway from Heaven since I saw Waynes World in the third grade. What was your opinion on the documentary?
