Keep in mind that Krautrock is not much of a genre. There are vast differences between the bands that fall into that category. For example, Can's an outlier with its jazz/funk/avant-garde influences; so's Amon Düül in all its myriad DIY forms; noise bands like Faust don't have much in common with melodic and occasionally ambient groups like Ash Ra Tempel, Cluster (and its spinoffs), Kraftwerk, NEU! and Tangerine Dream. There's a lot there. If you don't like something, it's a good idea to listen to something else instead, it's likely to be very different.
