Query: Very Disappointing

Don't. waste your money on the Blue Ray. The sound quality was a huge let down. Sounds like stereo, not state of the art 5.1Way too much filming of the audience. It's. also hard to understand what Adele is saying when she talks between songs.She's. a great singer and we all love her music. It's. too bad the audio and video was butchered by the producer.
