The Hoff is a legend who has entertained millions, as have TH. I don't know about the Berlin Wall but there are a lot of teens worldwide who, because of Tokio Hotel, are learning the German language and know more about German ways and culture than would otherwise have been the case.
If people are more interesting in a culture, then how could it not be positive? Regardless of your assessment of TH
Edit: ...strange, I thought someone else posted that...
