I'm appalled by the rather vultural reaction by the dutch and british far right, surprised by the german's ability to keep calm and carry on and also just sad.
The German far right is at with full force too... and calm isn't that abundant either, esspecially among the Conservatives (the bavarian prime minister was quick to re-take the field with his anti-immigration stance, for example) ...
The media's calm has a lot to do with lessons learned over the past two years (maybe even longer); recently it seems there have been a lot mlre stories that sparked viseral reactions from "the audience", esspecially over issues like.migration and refugees, that lead to the development of a sense of responsibilty...
however there are the usual suspects doing their usual thing (e.g. Bild supposidly titled "ANGST!" - for those not in the know: Bild is more a tabloid but highly popular due to their style of reporting)
Additionally, police failing their PR in wake of major crimes is as a common as everywhere else but the Berlin and Federal police seemed to have learned from the PR failure the police in Munich crwated after a mass shooting earlier this year..
On the other hand if it were any other city things might be different:
The common prejudice against the citizens of Berlin is that they are hard to disturb and rather defiant bordering to dismissiveness. That image helps to cultivate a sense of calm as everyone outside Berlin can basically "rest assured" that it hit the wrong people to be effective.
It is also a good thing that there is an abundance of Berlin citizens to help back up this view in this time. Berlin's communities have a long history of "making due with each other" and standing together despite the differences (since they are really abundant) is a rich tradition which no gentrification has been able to erase so far.
