I do not hate, but the following I generally dislike:

* any "boy band"
* any "girl band"
* any typical jazz (big) band
* commercial / popular bands not caring for interesting (or even good-quality) music
* bands consisting of very young people unless they are interesting or potentially will be
* bands having fake attitude to show

Up there is it in general. I could be specific using detail but it would require much time.
