Query: Poor quality DVD

This DVD needs some fine-tuning. I wish Mariah would have added a different grouping of songs and titled it differently. She doesn't seem to be going around the world (she only went to a few cities) and it would have been more interesting to make the songs sound differently. Time after time, I get the feeling that she wants to show her vocal range, which is great, but after a while, we all want some variety.
