Query: "What a disappointment"

My father bought this DVD and said that it is 75% commentary and critical review and only 25% music.While the person was talking, the music was playing in the background but you can hardly hear it.He really wanted to hear music and see a performance but got too much talking. He's not a new fan of Abba. He owns four other DVDs and some CDs and he enjoys all of them.For a DVD at this price, it isn't worth it.
