I cannot speak for anyone else, but while Adele has a few songs I can handle, her over the top singing style makes it hard for me to get any emotional reaction from her songs. In essence, the way she sings most of the time reminds me of a guitar player who feels the need to shred like crazy in every solo, simply because they can. She obviously was gifted with a great voice from the gods, but her "I am going to show off how awesome my voice is in every line, even when a little more restraint is needed" style of singing just isn't my thing.
